Lifetime optimization and security are two important design issues for multi-hop wireless sensor networks with non-replenishable energy resources. In this research, we propose a novel secure and energy aware (SEAR) routing protocol to address these two issues concurrently through balanced energy consumption and probabilistic random walking. SEAR is designed with two configurable parameters, energy...
Sensors are energy constrained, which leads to possible selfishness as the sensor may decline to forward packets for other nodes. Sensors also face the problem of unfair depletion of their energy if communication protocols were energy-unaware. To address the above concern, we propose the dynamic Bayesian game approach: our algorithm derives mutually acceptable path selection strategies between the...
In the last few years, wireless sensor networks have gained a lot of interest in the research field. WSNs consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing protocols have been proposed for WSNs. Most of the hierarchical algorithms proposed for WSNs concentrate mainly on maximizing the lifetime of the network by trying to minimize the energy consumption,...
