Load reduction with multiple mobile sinks in wireless sensor networks

Abstract

Uniform load distribution is a major challenging area in wireless sensor networks. Sink mobility strategy achieves great success in uniform load distribution policy. In optimal sink mobility scheme, main problem is optimal path construction for sink movement with minimum message overhead. This paper reports an optimal path construction strategy for mobile sinks movement in wireless sensor network. Proposed sink mobility scheme increases network throughput as well as conserves energy by optimal path construction. The proposed scheme divides whole network into sub regions, and they are coupled with quad tree. Mobile sink collects data region wise. The quad-tree based sink mobility scheme reduces energy consumption rate through uniform load distribution. The experimental results verify the effectiveness and feasibility of the proposed work.
