Cooperative ARQ techniques for wireless networks

In most of the infrastructure networks, in which all terminals communicate through an access point (AP). In such scenarios, the AP can gather information about the state of the network, e. g., the path-losses among terminals. Cooperative ARQ techniques can be useful for selecting a best mode based upon some network performance criterion. It is propose that a DF-HARQ (Decode and forward hybrid ARQ) Protocol which enhances throughput of the system. Base station will select a cooperative mode based upon some network performance criterion, and feed back its decision on the appropriate control channels. Here cooperative diversity lives across the throughput performance of the network. The protocol model and performance analysis to evaluate the throughput of the network is demonstrated.
