Wireless relay network consist of distribution of network topology commonly used in wireless network. Where it sender and receiver are interconnected by mean some of mobile nodes. Relay technology are used enhance packet delivery and increase performance of wireless networks such as worldwide interoperability for microwave access and LTE-A. Later developed Automatic Repeat Request (ARQ) technique that to reduced packet lose and increase latency but the authors recognizes potential drawbacks of automatic repeat request techniques that's are ambiguous error report, packet overhead and number of acknowledgement in case of successful received data.
