Abstract:
This paper provides and evaluates many simulation results concerning the energy consumption in WSN under different assumptions for various scenarios, including the impact of the routing strategy, broadcast delay, data aggregation, data rate, and the significant effect of MAC selection and configuration of its parameters. For simulations we analyze first the node’s behavior in terms of energy consumption and investigate the impact of different parameters on it. To that aim, we use our sensor network framework (SNF), a flexible tool to build various protocols by combining existing building blocks at different layers (i.e., we provide also complete energy-efficient MAC modules). In this simulation environment routing protocols can be rapidly developed, closely inspected and the effects of changing configuration parameters and their impact on the performance better investigated and analyzed. We illustrate this in case of a two phase adaptive energyaware routing protocol (with several routing metrics) as well as an enhanced, energy-aware directed diffusion and provide here various experimental results. After simulation and evaluation we are able to give guidelines for suited routing metrics and strategies, composition of protocols at different layers and how joint optimizations with MAC protocols increase the efficiency of routing.
