Structured Communication in Single Hop Sensor Networks

Abstract. We propose a model for communication in single-hop wireless sensor networks and define and evaluate the performance of a robust, energy balanced protocol for a powerful and general routing primitive (N, p, k1, k2) routing. This routing primitive represents the transfer of N packets among p nodes, where each node transmits at most k1 packets and receives at most k2 packets. Permutation routing is an instance of this primitive and has been recently studied by other researchers in the context of single-hop wireless radio networks. Our proposed protocol is the first to exploit the availability of a low-power control channel in addition to the "regular" data channel to achieve robustness in terms of handling node and link failures - both permanent and transient. We use a dynamic, distributed TDMA scheme for coordination over the control channel, which leads to collision-free transmissions over the data channel. The objective is to minimize overall latency, reduce per-nod...
