A multi-pair two-way relaying scenario with multi-antenna mobile stations is considered. The bidirectional communications between the mobile stations are supported by an intermediate non-regenerative multi-antenna relay station. It is assumed that the mobile stations can subtract the back-propagated self-interference. Different relay transceive filter design approaches which utilize the fact that...
Cooperative communication when other mobile nodes could act as potential relays, poses significant challenge in designing relay selection algorithms due to the information asymmetry between the source and the potential relays. The potential relays in this case are better informed about their channel conditions than the source. Therefore, the source must provide them with incentive to reveal their...
In this paper we study multi-copy routing schemes in opportunistic networks. Compared to single-copy protocols, the multi-copy schemes expedite the mean delivery delay while consuming more resources and exposing lower packet delivery ratio in resource-constrained system. To enhance the system capacity, most recent works explore the impact of social structure on network performance. Their results indicate...
