Impact of Mobility on BER in Wireless Cooperative Networks

An efficient approach called cooperative communication has been proposed that allows mobiles achieve uplink transmit diversity by relaying each other´s messages. In this paper, we study performance of wireless cooperative networks consisting of a given number of users each moving according to the random waypoint mobility model. We define the dynamic cooperation BER for evaluating the relative performance improvement of wireless networks. We use amplify-and-forwards as relaying schemes to illustrate the validity of the cooperative communication in the case of dynamic partner choice.
