Abstract
An important issue in wireless sensor networks is the limited availability of energy and hence optimizing energy is very important. We propose a new scheme to reduce the energy consumption of nodes during packet transmission based on queue threshold by considering node failures into account. We develop an analytical model of a sensor network and analyze the performance of the proposed scheme in terms of performance parameters such as average energy consumption and mean delay considering node failures. We also derive the expression for the optimal value of threshold. Results show that the average energy consumption savings is 68% for the optimal threshold value when compared to no threshold condition and mean delay increases as failure rate increases. We perform simulations and the results obtained show that the analytical results match with the simulation results thus validating the analytical model.
