Abstract

Transmitting a packet through two node-disjoint paths can improve the end-to-end reliability. The Parallel Redundancy Transmission (PRT) method in Multi-Channel Multi-Radio Wireless Mesh Networks (MCMR-WMN) is studied in this paper. In this method, a packet is simply duplicated in the first mesh router it arrives, then the two copies are transmitted through two node-disjoint parallel paths to the destination. The destination node only receives the earlier arrived one. We focus on the analysis of average end-to-end delays of Poisson ows. The analysis bases on the queueing network theory. And the packet loss rates on links are considered. The numerical results demonstrate the accuracy of the end-to-end delay analysis.
