ABSTRACT: COPE is an architecture for wireless mesh networks that improves the overall throughput of a network using opportunistic coding. COPE’s performance has been analyzed by different researchers and modifications to this architecture have been proposed that further improved the throughput of a network. Two simple network topologies were analyzed using COPE in research work presented in [1]. In this research paper, this idea has been extended to three other network topologies. Coding gains for these networks are mathematically formulated and COPE’s performance is analyzed when applied to these networks. On the basis of this analysis, the gains of these networks, which are obtained as a result of opportunistic coding, are compared with each other. Simulation results also help to analyze the performance of networks in COPE and non-COPE cases.
