Performance Analysis of Grouping Strategy in Relay-Based Cooperative Networks
Grouping method is an efficient transmitting mechanism in a relay-based cooperative networks. The grouping strategy in this paper focus on finding out the best two quality of links from user to neighboring relays, and the user accesses the same channels within the best and second best relays. In this paper, we proposed an analysis model using Markov process to evaluate the system performance, grouping success rate. Through comparing the results between the numerical and simulation results, our proposed analysis model and method can provide an efficient way to evaluate the performance under the grouping strategy in relay-based networks.
