Abstract: Mobile sink reduces the energy consumption of nodes and prevents the formation of energy holes in wireless sensor networks(WSNs).These benefits are dependent on the path taken by the mobile sink, especially in delay-sensitive applications, as all sensed data must be collected within a given time constraint. So,a hybrid moving pattern is formed in which a mobile-sink node only visits rendezvous points (RPs), as opposed to all nodes. Sensor nodes that are not RPs forward their sensed data via multihopping to the nearest RP........
