The resource limited nature of WSNs requires that protocols implemented on these networks be energy-efficient, scalable and distributed. In this paper, the authors present a novel combined routing and MAC protocol. The protocol achieves energy efficiency by minimizing signaling overhead through stateless routing decisions that are made at the receiver rather than at the sender. The protocol depends on a source node advertising its RSSI to its neighbors, which then contend to become the receiver of the packet, by measuring their local optimality index, and map this into a timer value.
