Adaptive Reliable Routing Protocol for Wireless Sensor Networks

International audienceMany Wireless Sensor Networks (WSN) applications success is contingent upon the reliable delivery of high-priority events from many scattered sensors to one or more sink nodes. In particular, WSN has to be self-adaptive and resilient to errors by providing efficient mechanisms for information distribution especially in the multi-hop scenario. To meet the stringent requirement of reliably transmitting data, we propose a lightweight and energy-efficient joint mechanism for packet loss recovery and route quality awareness in WSNs. In this protocol, we use the overhearing feature characterizing the wireless channels as an implicit acknowledgment (ACK) mechanism. In addition, the protocol allows for an adaptive selection of the routing path, based on a collective cooperation within neighborhood
