Abstract:
In this paper we extend our previous implementation of the T-MAC protocol inside the sensor network simulator with a receiver-based routing (RBR) service and we propose and implement several performance optimizations. We investigate the impact of several MAC protocol parameters (listen time, receiver contention window, radio switch time, etc.) on the performance of routing protocols used in resource constrained wireless sensor networks. The main performance criteria we are interested in are the energy consumption (reflected by the active time the node is operational), the throughput and latency of the network in delivering replies to users' requests. Simulation results have shown that using the proposed optimizations improve significantly the performance of the RBR. Moreover, we compare the performance of receiver-based routing against the unicast within our implementation of the T-MAC protocol. Although in direct comparison the RBR approach is outperformed by unicast, we show that RBR can be efficiently employed for opportunistic aggregation inside monitoring areas with many sources or in dynamic network scenarios.
