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

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. [ABSTRACT FROM AUTHOR]
