Recent large system analyses have shown that the per-node throughput of purely broadcast wireless networks goes to zero as the size of the network increases. Importantly, the problem appears to be physical in nature, i.e., it cannot be overcome through clever protocols, codes, or modulations. This fundamental problem, along with the proliferation of wireless devices that are able to communicate over...
Design and analysis of cooperative communication schemes based upon modeling and simulation exist in large quantities in the research literature. Despite this fact, there have been relatively few efforts directed toward implementing and experimentally evaluating such schemes. Cooperative protocols have many components that make them challenging to implement in real-world radio architectures, and their...
Cooperative diversity is a useful technique to increase reliability and throughput of wireless networks. To analyze the performance gain from cooperative diversity, outage capacity is an important figure of merit that captures the inherent diversity-multiplexing trade-off in cooperative diversity schemes. In this paper we derive the outage capacity for several cooperative diversity schemes in decode-and-forward...
