An energy efficient data aggregation technique using multi-sink infrastructure in heterogeneous wireless sensor network

Abstract

The energy consumption of sensors adjacent to sink or upon critical paths remains excessively fast along with additional drawbacks in wireless sensor networks using single sink node. Therefore, we propose Energy-efficient secondary level base station (EE-SLB) based data aggregation in wireless sensor network. Multi-sink infrastructure permits sensor nodes for choosing various sink nodes with respect to their individual situation compared to single-sink topology. As a result, the usual transmission distance amid sensor nodes as well as sink nodes may be decreased. The benefits of dispersion, stability as well as robustness are given by the deployment of multi-sink nodes.
