Optimum Location-Based Relay Selection in Wireless Networks

This paper studies the performance and key structural properties of optimum location-based relay selection policy for wireless networks consisting homogeneous Poisson distributed relays. The distribution channel quality indicator at location is obtained. A threshold-based selective feedback proposed discovery with finite average load. It established that total number relays feeding back obeys a an analytical expression load derived. expressions rate outage probability without are obtained general path-loss models. shown outperforms other common strategies notably. also utilizing information from five on enough to achieve almost same infinite case. As generalizations, isotropic point processes heterogeneous source-to-relay relay-to-destination links studied.
