An implementation of Automatic Repeat reQuest (ARQ) mechanism in cooperative wireless networks using max-ratio relay selection

Abstract

Now-a-day, relay technology has been adopted to improve the coverage, reliability and quality-of-service in wireless network. This paper proposed a new relay selection method with Automatic Repeat reQuest (ARQ) scheme. In this paper, multiple relay are used to transmit the data from source to destination node by using max-relay. To find proper node this paper proposed a new relay selection method based on euclidean distance method. This paper also proposed an Automatic Repeat reQuest (ARQ) mechanism i.e. stop and wait Automatic Repeat reQuest (ARQ) scheme. When any error occurs in the relay at data transmission time then relay use Automatic Repeat reQuest (ARQ) strategy. This new scheme proposed for reduce the packet loss, network loss and delay on the wireless network.
