ABSTRACT: Although many ways to communicate with someone, SMS is still one of the popular media to send a message to someone. Not unlike the others, the messages sent can be known by the third party either tapping or the investigation. Unencrypted SMS can be easily obtained from communication providers so that they may be misused. Since the communication devices have been using Android operating system, they are programmable. There is various script can be inserted to devices to protect the data......

ABSTRACT: Routing protocols are the basic process mechanisms needed to route the packets from one node to another node in Mobile Ad Hoc Networks when nodes are not within the transmission range. The performance of these routing protocols is affected by various factors in particular node density, mobility model, transmission range, etc.. In this paper, simulation studies are conducted to analyse the performance of two proactive (DSDV and OLSR) and two reactive (DSR and AODV) routing protocols using different traffic classes. The performance of these routing protocols are analysed by using QoS performance metrics like packet delivery ratio, throughput, end-to-end delay, normalized routing overhead and jitter............

ABSTRACT: The popularity of Geographic Information System (GIS) has grown tremendously such that software developers can no longer neglect that sector when fashioning out new technologies for software development. The concept of Object-Oriented Programming (OOP) has revolutionalised software development industry including the GIS and software modeling in general. This paper reveals how the concepts inherent in Object-Oriented Programming Languages (OOPLs) can be deployed to model a GIS software.......

ABSTRACT: Mobile phone is one of the most widely and extensively used devices for communication across the world for both personal and business activities. The capabilities of mobile phones have been improving very quickly in terms of computing power, storage, feature support, and developed applications. Mobile Cloud Computing simply refers to an infrastructure where both the data storage and the data processing are made to happen outside of the mobile phones. With the advent of cloud services for mobile application, it has greatly enhanced the scalability and security. Hence, it stores contact numbers and messages sent from different mobile users in its memory and SIM card..............

ABSTRACT:Decision making is one of the most important aspects in order to enhance service delivery to citizens and businesses, gain more profit, and help stakeholders to strategize their business functions. Nowadays, most of the stakeholders make decisions based on the data that is precise, concise, appropriate, and accurate. Even though Big Data Analytic (BDA) tools and software can assist in this matter, skills and competency of the personnel that handle and manage the data is more crucial and important. Thus, the aim of this paper is to identify data scientist skills from global best practices and examine the most important data scientist skills required by Information Technology (IT) personnel.......

ABSTRACT: Power based connectivity is an ad hoc research topic. Implementing power control mechanisms enhance network life and to improve throughput, locate cost effective routes and spatial reuse. This paper uses MAC protocol to implement coordination functions and power control mechanisms through the use of fuzzy rules generated by upper network layers using two input variables like link quality and node neighborhood count with optimal power consumption level as the output variable. Experiments using fuzzy rules are compared to DSR routing and two hop power control methods. Result showed that two hop power control with fuzzy logic method yields lower route discovery time, increased cache replies, minimum simulation time and end to end delay when compared to DSR routing and two hop routing protocol.

ABSTRACT: This research will aid organizations in identifying opportunities for improvements and developments that will remain relevant as students' evolve from academic to professional life. Organizations will be enlightened on the impact mobile devices have on students, and how these devices could be helpful and some damaging to the welfare of students. Additionally, even though scholars have carried out various researches on mobile devices and students, focus has been based majorly on the role mobile devices plays in student's social life rather than academic life; this then is the gap this research aims to bridge.........
