Equitable Energy Consumption During Repeated Transmissions in a Multihop Wireless Network

This paper addresses the issue of network life during repeated broadcasts originating from the same source in large, strip-shaped wireless sensor networks. The proposed technique would also apply to a unicast over a strip-shaped cooperative route within a network. The proposed Medium Access Control (MAC)-free "Alternating sets" transmission strategy is based on a very low-overhead form of cooperative diversity called the Opportunistic Large Array (OLA). The proposed Alternating OLA with Transmission threshold (A-OLA-T) uses a received power-based threshold to define mutually exclusive sets of nodes, such that the union of the sets includes all the nodes in the network or cooperative route during the initial broadcast.
