Multi-Path Relay Selection Based on Radio and Television Business

Abstract

This paper presents a relay selection method for radio and television business, this method uses nodes time-delay and power information, obtains the value of network interrupt as decision threshold, then selects the relay node. At same time this paper proposes an optimal relay selection strategy which can minimize the network interrupt probability combination with power distributionMulti-Path Relay Routing Protocol, this protocol can change the appropriate route path according to the dynamic network. Simulation results show that this protocol can extend cells coverage area, reduce time-delay and increase system throughput, improve system spectral efficiency, and enhance Qos of radio and television business.
