In this paper, the sub-optimal power allocation relay selection (SBS-AF) algorithm in multiple-input multiple-output (MIMO) relay networks was proposed. The energy efficiency and the symbol error rate (SER) in multiple antennas MIMO relay networks is investigated. Amplify andforward (AF) relay scheme, where N relay access point(s) occupied with Q antennas cooperatively forwards packets to the d...
Recently, many researchers have been attracted to intermittently connected mobile ad-hoc networks (MANETs), which are a type of DTN (delay/disruption/disconnect tolerant network). To achieve end-to-end communication between a source node and a destination node in the networks, storecarry-forward routing has been considered as a promising solution. In this paper, we propose an algorithm for opti...
The limiting effect of multi-user interference from an adjacent cell upon the relays used for cooperative transmission is considered in the context of legacy networks which adopt max(min(·, ·)) type relay selection policies. We extend previous work which considered single relay selection to the selection of two or four such relays, as is required in distributed space–time coding. We obtain new ...
