Comparison of routing protocols in wireless sensor network using mobile sink- A survey

Wireless sensor network consists of various sensor nodes which sense the environment and forward the sensed data to the sink node. Routing in static wireless sensor network sensor nodes near the sink consume all its energy there by network partition occurs (hot-spot problem). To avoid hot-spot problem a routing in wireless sensor network using mobile sink can be used, where a sink node is provided mobility which gathers information from the sensor nodes using 1-hop communication there by reduces a hot-spot problem and increases network lifetime and decreases energy consumption. In this paper types of wireless sensor network are presented, various routing protocols in wireless sensor network using mobile sink is also presented. At the end of the paper a detailed comparison of surveyed routing protocols is also presented.
