Receiver-Based Routing Service for T-MAC Protocol

In this paper we extend our previous implementation of the T-MAC protocol inside the sensor network simulator with a receiver-based routing service (RBRS) and we propose several performance optimizations. We investigate the impact of several MAC protocol parameters 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. To that aim, we use our sensor network framework, a flexible tool to easily build various protocols by combining existing building blocks at different layers, that enables us to inspect closely the effects of different configuration parameters and their impact on the performance.
