Parallel Opportunistic Routing in Wireless Networks

The authors study benefits of opportunistic routing in a large wireless ad hoc network by examining how the power, delay, and total throughput scale as the number of source-destination pairs increases up to the operating maximum. Their opportunistic routing is novel in a sense that it is massively parallel, i.e., it is performed by many nodes simultaneously to maximize the opportunistic gain while controlling the inter-user interference. The scaling behavior of conventional multi-hop transmission that does not employ opportunistic routing is also examined for comparison. Their results indicate that their opportunistic routing can exhibit a net improvement in overall power-delay trade-off over the conventional routing by providing up to a logarithmic boost in the scaling law.
