Optimal Placement of Multisinks in Wireless Sensor Network for Lifetime Improvement Network

摘要

sensor nodes are powered by batteries and proper energy conservation is needed to prolong the lifetime of the sensors. This work proposes an approach for improving energy-efficiency and thus increasing network lifetime in wireless sensor network (wsn) using a logical energy tree (let). In our scheme, let is constructed using the remaining available energy in each node. Multiple sink nodes are placed in sensor network and routing of packets from sensor nodes is done using let to the centralized sink or to the closest sink. Multiple sinks are placed in a optimum manner such the number of hops for transmission is reduced and due to it the life time of the network is increased..
