Most of the existing routing protocol designed for WSNs assume that links are symmetric which is in contradiction to the reality of these networks. Indeed, asymmetric links cannot be ignored in WSNs as they can be predominant. The apparition of asymmetric links can dramatically decrease routing protocols that are not designed to support them by decreasing(More)
In Wireless Sensors and Actuators Networks (WSANs), actuator nodes are nodes richer in resources (processing capacity, power transmission and energy storage) and better suited than sensor nodes to process the data, make decisions based on sensed values and perform appropriate actions. In addition, in order to provide timely action, coordination between(More)
Most existing routing protocols designed for WSNs assume that links are symmetric, which is in contradiction with what is observed in the real deployment. Indeed, many links in WSNs are asymmetric. Asymmetric links can dramatically decrease the performance of routing algorithms which are not designed to cope with them. In this paper, we propose two(More)
