FEESR: Framework for energy efficient secured routing in heterogeneous sensor network

The security routing protocols practiced in a wireless sensor network are not enough to thwart the potential security breaches in heterogeneous wireless sensor networks. After reviewing the existing research methodologies to resist the adversaries, it was found that existing techniques are either computationally expensive process or lead to communication overhead. Therefore, this paper presents a novel framework called as FEESR i.e. Framework for Energy Efficient Secure Routing in the heterogeneous wireless sensor network. The novelty of FEESR is its mobility model, the algorithm for the key generation, and validating the keys, which is simpler, lightweight, non-recursive and doesn't generate any communication problems. The proposed mechanism of FEESR adopts an analytical approach and found to exhibit better energy and throughput performance in comparison to the standard hierarchical algorithm.
