A Resource Allocation Algorithm for Cluster-based Cooperative MIMO in WSN

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Energy efficiency is a considerable criterion in design of wireless sensor networks. MIMO technology has the potential of supporting a higher data rate under a lower power budget and bit-error-rate, which makes cooperative MIMO in WSNs a popular research topic. This paper investigates a cluster-based time division cooperative MIMO communication system for WSNs. An optimum algorithm for the power and time allocation for an intra-cluster and inter-cluster slot has been proposed. By introducing two adjusting parameters for the energy and the time slot respectively, this algorithm is designed to achieve the maximum data throughput for one single-hop and at the same time remain within the tolerance of the outage probability requirement. Performance of different STBC schemes using such an optimum algorithm and the SISO transmission method are compared by simulation.
