Executive Summary

Opportunistic routing has been shown to improve the network throughput, by allowing nodes that overhear the transmission and closer to the destination to participate in forwarding the packet, i.e., in forwarder list. The nodes in forwarder list are prioritized and the lower priority forwarder will discard the packet if the packet has been forwarded by a higher priority forwarder. One challenging problem is to select and prioritize forwarder list such that a certain network performance is optimized. In this paper, the authors focus on selecting and prioritizing forwarder list to minimize energy consumptions by all nodes. They study both cases where the transmission power of each node is fixed or dynamically adjustable.
