Abstract: This paper shows a protocol for converge casting in wireless sensor networks. It features the cross-layer integration of geographic routing with contention-based MAC for relay selection and load balancing, as well as a mechanism to detect and route around connectivity holes. This technique solves the problem of routing around a dead end without overhead-intensive techniques such as graph planarization and face routing. This protocol is localized and distributed, and adapts efficiently to varying traffic and node deployments. Through extensive ns2-based simulations, we show that this protocol significantly outperforms other converge casting protocols and solutions for dealing with connectivity holes, especially in critical traffic conditions and low-density networks. Our results show this is an energy-efficient protocol that achieves remarkable performance in terms of packet delivery ratio and end-to-end latency in different scenarios, thus being suitable for real network deployments.
Keywords: cross-layer routing, connectivity holes, geographic routing, localization errors.
