R.latha, T.n.prabakar, G.jegajothi, V.prasanna Venkatesh . An Energy Aware Multiple Sink Repositioning Algorithm for Improving Lifetime in Wireless Sensor Networks. International Conference on Communication, Computing and Information Technology. ICCCMIT2014, 2 (March 2015), 33-36.
In Wireless Sensor Networks, potential sink selection and sink movements are costly in terms of node energy. In this paper, we propose K -Partitioned Minimum Depth Tree using the optimal search in Placing Optimal Number of Sinks in Sensor Networks for improving the Network Lifetime Maximization. Initially the optimal number of sinks is determined using the optimal sink algorithm satisfying the h-hop constraint. Then a K-Partitioned Minimum Depth Tree (k-PMDT) is constructed for positioning multiple sink nodes and setting up the routes. After determining the optimal number of sink positions and routing, best sink reposition is selected by optimum search method. Link movement is done by intelligent movement and it limits the sinks movements while maintaining their direction to the optimal positions. The main advantage of this method is to improve the lifetime of WSN's.
