Multi-Rate Combination of Opportunistic Routing and Network Coding: An Optimization Perspective
Recently, wireless communication methods that exploit the broadcast nature of the wireless medium have been attracting growing attention. Among these methods, opportunistic routing and network coding are regarded as the most promising techniques. While there have been some attempts to combine opportunistic routing with network coding to capture the advantages of both techniques, none of these attempts has considered bit-rate selection for data transmission in multi-rate wireless networks. In this paper, the authors study the potential benefits of the combination of opportunistic routing and network coding with the bit-rate selection mechanism from an optimization perspective.
