Abstract: In our project, we propose an optimized version of the FCFS scheduling algorithm to address the major challenges of task scheduling in cloud. The incoming tasks are grouped on the basis of task requirement like minimum execution time or minimum cost and prioritized (FCFS manner). Resource selection is done on the basis of task constraints using a greedy approach. The proposed model will be implemented and tested on simulation toolkit. We intend to create a module depicting the normal FCFS algorithm in comparison to our optimized version algorithm for resource provisioning in the cloud.

Abstract: Peer-to-Peer (P2P) communications and its applications have become conventional architecture in the wired network environment. However, they have not been effectively adapted to the ensemble mobile environment which composed of various devices such as smart mobiles devices, laptops, and device with embedded software. In P2P systems, each node can act as a client and as a server at the same time and shares with others its own data. Our contribution consists in designing, implementing and testing a BitTorrent like application adapted to wireless ad-hoc networks of Android Mobile Phones. The employment of P2P protocols and applications in the platform of the ensemble mobile environment is becoming a promising solution which permits a wide number of users to share their own contents (data, audio, video, etc.) and communicate with each other without using costly and centralized network infrastructure. By using a central server, the peers will be able to get the information about the contents of other peers. Even in the absence of the Internet, the mobile devices provide users with the potential opportunity to connect in ad-hoc manner via short range wireless protocol such as Wi-Fi.

Abstract: Technology has been touching our lives in almost every domain. With the advent of modern technologies, the need of enhancing its security also arises. Data security has become one of the most important issues of concern. Data security is achieved with the help of adapting certain security measures. Here, in this paper we have analyzed the various cryptographic concepts. Encryption and decryption are two most important aspects of cryptography and data security. The special light has been thrown on data integrity and protection issues. The RSA algorithm has been explained. The implementation of the algorithm has also been given with the help of proving a graphical interface. The data integrity has been established at the client and receiver end by not limiting it to a standalone application.

Abstract: The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security. The recent denial of service attacks on major Internet sites have shown us, no open computer network is immune from intrusions. The wireless ad-hoc network is particularly vulnerable due to its features of open medium, dynamic changing topology, cooperative algorithms, lack of centralized monitoring and management point, and lack of a clear line of defense. The traditional way of protecting networks with firewalls and encryption software is no longer sufficient and effective. Many intrusion detection techniques have been developed on fixed wired networks but have been turned to be inapplicable in this new environment. We need to search for new architecture and mechanisms to protect wireless networks and mobile computing application. In this paper, we examine the vulnerabilities of wireless networks and say that we must include intrusion detection in the security architecture for mobile computing environment. We have showed such architecture and evaluated key mechanisms in this architecture such as applying mobile agents to intrusion detection, anomaly detection and misuse detection for mobile ad-hoc networks.

Abstract: Protein sequences have been considered for a long time as highly complex sequences from the informational content point of view. We study about the randomness of protein and difficulty of protein compression. In this report, we propose a lossless compression method to reduce the random or repeated sequence of protein. Our proposed method is the enhancement of Dictionary Based Algorithm proposed by D. Adjeroh and F. Nan. They have shown better result in compressing protein. Our repeat reduction method shows improved results in compressing three types of protein sequences from MJ (Methanococcus jannaschii), HI (Haemophilus influenzae) and HS (Homo sapiens). The experimental results demonstrate that the performance of the proposed method is superior compared to Dictionary based algorithm.

Abstract: As far as security is concerned compromised system plays a vital role i.e., system connected with a network and which is used to send spamming, malware, identity theft etc. A System is developed mainly to focus on detection of compromised machines which is already being affected by hacker or cracker and used for anti social activities. We have developed an effective solution for detecting compromised system named "SPOT". SPOT uses SPRT (Sequence probability ratio test) which has false positive and false positive error rates. This SPOT is an effective and efficient system in detecting compromised machines in the network. To implement a single remote address corresponds to a malicious scanner which works good in internet environments. The main objective are effectively identifying the spam zombies and Denial of Services attack using SPOT without any botnet spam signatures techniques on the network. Keywords- Compromised machines, Malicious scanner, Spam filter, Machine creation, dynamic ip, Spam zombies.

Abstract: In the network environment firewall is one of the protection layers. A firewall policy defines how an organization's firewalls should handle inbound and outbound network traffic for specific IP addresses and address ranges, protocols, applications, and content types based on the organization's information security policies. In this paper, we propose a set of firewall policy to support distributed environment of firewalls. We also represent a set of firewall policies to automatically detecting and resolving anomalies in the network layer. we adopt a rule-based segmentation technique to identify policy anomalies and derive effective anomaly resolutions. we demonstrate how efficiently our approach can discover and resolve anomalies with conflict packet and resolved packets.

Index terms- Firewall, policy anomaly management, access control, visualization tool, anomaly.

Abstract:MultiMedia is growing application in various areas ,security is an important issue in communication and storage of images and Encryption is a very common technique to uphold image security. Many encryption systems have been introduced among them; image encryption using chaotic sequence has many proposals. In this paper we analyze the security weakness of the proposal. We use chosen plain-text attack and known plain-text attack to reveal the secret parameters of the algorithm. That is to say, this method is not at all secure from the point of cryptography.

Abstract: Cloud computing is a model for enabling convenient, on -demand network access to shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort . As the problem of building scalable trans-action management mechanisms for multi-row transactions on key-value storage systems . For that purpose we develop scalable techniques for transaction management by using the snapshot isolation (SI) model. This SI model can give non-serializable transaction executions, we investigate two conflict detection techniques for ensuring serializability under SI. As getting importance of scalability, we investigate system models and mechanisms in which the transaction management functions are decoupled from the storage system and integrated with the application-level processes. We present two system models and demonstrate their scalability under the scale-out paradigm of Cloud com-putting platforms. In the first system model, all transaction management functions are executed in a fully decentralized manner by the application processes. The second model is based on a hybrid approach in which the conflict detection techniques are implemented by a dedicated service.

Keywords- cloud data, scalable transaction, SI model , serialization , decentralization.

Abstract: Contrast stretching is a method to enhance the image details. Histogram equalization is one of the most common spatial domain technique used for contrast enhancement. While stretching the contrast of an image , it results in the degradation of brightness of the image. To overcome this hurdle a method known as Bi-Histogram equalization was introduced to preserve the brightness level of the output image. As the contrast enhancement enhances the image , it also enhances the noise in the signal that causes the blurrness in the output image. The proposed BHEGF method reduces this drawback and provides more accurate and realistic results. In this paper we use four different types of filters i.e. median filter , gaussian filter , average filter & motion filter and various parameters such as processing time , MSE, brightness count and PSNR are used for performance evaluation.

Abstract: The paper shows performance comparison of three proposed methods with orthogonal wavelet alias Cosine, Haar & Walsh wavelet using Normalization for 'Color to Gray and Back'. The color information of the image is embedded into its gray scale version using wavelet and normalization method. Instead of using the original color image for storage and transmission, gray image (Gray scale version with embedded color information) can be used, resulting into better bandwidth or storage utilization. Among three algorithms considered the second algorithm give better performance as compared to first and third algorithm. In our experimental results second algorithm for DCT wavelet using Normalization gives better performance in 'Color to gray and Back' w.r.t all other wavelet transforms in method 1, method 2 and method 3. The intent is to achieve compression of 1/3 and to print color images with black and white printers and to be able to recover the color information as and when required.

Title : Comparative Study of RBFS & ARBFS Algorithm
Country : India
Authors : Disha Sharma, Sanjay Kumar Dubey
: 10.9790/0661-105105110      logo

Abstract: RBFS is a best-first search that runs in space that is linear with respect to the maximum search depth, regardless of the cost function used. This algorithm allows the use of all available memory. One major flaw of this algorithm is that it can visit the same node several times. This makes the computational cost may be unaffordable for some accuracy. This problem can be much solved by using various extension of Heuristic Search. By using anytime approach in our simple RBFS will improve solution by saving the current solution & continues the search. Anytime RBFS algorithm will optimize the memory & time resources and are considered best for RBFS algorithm. When the time available to solve a search problem is limited or uncertain, this creates an anytime heuristic search algorithm that allows a flexible substitution between search time and solution quality. Some applications like Real Time Strategy (RTS) games have applied these algorithms to find a fast solution that will help the algorithm prune some paths during the subsequent computation.
