Abstract: Cognitive radio technology is an emerging technology which is very promising and hence is being developed at a rapid rate. In Multi Input Multi Output Cooperative Cognitive Radio Networks (MIMO-CCRN) primary users (PUs) recruit some secondary users (SUs) to cooperatively relay the primary traffic. Considering networks with heterogeneous services, it will be difficult to allocate the resources and assign the channel. The selection of secondary users (SU) as relay nodes should satisfy the rate and delay constraints of respective SUs. To overcome these issues, in this paper we develop an efficient resource allocation technique which uses very reliable nodes for data transmission. The resources are allocated only after ensuring that the nodes satisfy the specified constraints. This leads to successful data transmission and hence good network performance.
