A Bully Approach for Competitive Redundancy in Heterogeneous Wireless Sensor Network

In this paper, we address the recurrent problem of node redundancy in heterogeneous Wireless Sensor Networks (WSNs). In addition to presenting a new analytical approach for estimating redundancy and unlike existing works, we propose a new solution where sensors are competing for the identification and relocation of redundant sensors. In our solution, which is mainly based on a comprehensive formulation of redundancy as a dynamic matter, sensors with low redundancy weights force neighboring peers with high redundancy weights to relocate or go to sleep according to a bully strategy. First simulations with the ns3 tool are showing promising results.
