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

Abstract

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  I-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.
