Performance analysis and enhancement for a cooperative wireless diversity network with spatially random mobile helpers
In many studies on wireless cooperative diversity, it is often assumed that the number of helpers and their locations are deterministic or known a priori. In this paper, we relax such assumptions and investigate a wireless diversity system with distributed cooperation and spatially random helpers subject to random direction (RD) mobility. To enable opportunistic relaying with multiple helpers, ...

متن کاملPerformance Analysis of Cooperative Communication Wireless Network
In this paper, we analyze the performance of amplify and forward cooperative communication wireless network over Nakagami-m fading channel. We have calculated outage probability, channel capacity and ergodic capacity. We also verify the analytical equations of these parameters by plotting them using simulation
متن کاملPerformance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملPerformance Analysis of a Cooperative Wireless Network with Adaptive Relays: A Network-Level Study
In this work, we investigate the stability region, the throughput performance, and the queueing delay of an asymmetric relay-assisted cooperative random access wireless network with multipacket reception (MPR) capabilities. We consider a network of N saturated source users that transmit packets to a common destination node with the cooperation of two relay nodes. The relays are equipped with in...
