E-Cube Routing Protocol for Wireless Sensor Networks in the Presence of Network Failures

Abstract

Providing reliable communication represents one of the major barriers to wireless sensor networks. In this paper, we propose a fault-tolerant tableless routing protocol called E-cube + , inspired from e-cube routing protocol, to support intelligent rerouting. A range of fault-tolerant routing properties of E-cube + (such as loop-freeness, failure recovery guarantees, and bounded latency) have been derived and analyzed. Experiment results also show that E-cube + is able to route data properly without complicated and energy-intensive routing table lookup processes even when node failures occur.
