摘要：Due to recent trends in mobile communication system, much attention has be given to heterogeneous networks in which a mobile equipment is able to access multiple networks that are present in a locality. Here each random access networks (RANs) operates at different carrier frequency having different transmission bandwidth whose selection is based on the Quality Of Service (QOS) of each network. In this paper, we examine the efficient use of multiple radio access technologies (RATs) in cooperative network. By taking into account the circuit power consumption of each relay nodes, an optimal relaying scheme is introduced which outclasses the direct communication as well as the traditional best select relaying schemes producing effective packet transfer with reduced packet loss and increased throughput.
