Abstract

Routing is a key technique for wireless sensor networks (WSN). In order to improve the efficiency of routing in large-scale WSN, we propose Sink Routing Table (SRT) routing protocol, a routing protocol for WSN, in this paper. In SRT protocol, nodes aggregate data and use energy aware neighbor selection to route packets towards the target along an optimal path, each common node has no need to maintain a routing table, sink node maintain one instead. Our simulation results show that SRT is robust on large-scale networks and works well in the face of uneven network load and energy consumption.
