MATHEMATICAL ANALYSIS AND SIMULATION OF DISTRIBUTED OPTIMAL RELAY SELECTION IN WIRELESS MULTI-HOP COOPERATIVE SENSOR NETWORKS

In this paper, we investigate how to select the optimal relay nodes to provide the reliable and effective QoS provision and satisfy the diversity requirements of application services. The rest of the paper is organized as follows. The related work and our work are elaborated in describes the system models and problem description. In, we design a Markov chain model to describe process of data communication in wireless distributed sensor network and give the theoretical analysis model to show the achieved performance. The supported scheme of QoS diversity is used to realize reliable, efficient, and robust communication in wireless distributed sensor network, which is shown in proposes the QoS supported adaptive relay selection (ECA-Q-RS) approach, followed by the details of implementation.
