Abstract :
The opportunistic large array (OLA) with transmission threshold (OLA-T) is a simple form of cooperative transmission that limits node participation in broadcasts. Performance of OLA-T has been studied for disc-shaped networks. This paper analyzes OLA-T for strip-shaped networks. The results also apply to arbitrarily shaped networks that have previously limited node participation to a strip. The analytical results include a condition for sustained propagation, which implies a bound on the transmission threshold. OLA transmission on a strip network with and without a transmission threshold are compared in terms of total energy consumption.
