Performance Comparison of Survival Routing Mechanisms in Wireless Mesh Networks

Abstract:

This paper addresses the fault-tolerant mechanisms in Wireless mesh networks (WMNs), and designs a C++ based simulation platform to measure the performance of different fault-tolerant mechanisms. A comprehensive performance evaluation of network coding tree algorithm (NCT), 1+1 scheme and 1: N scheme in WMNs is conducted. Performance metrics, such as packet delivery ratio, resource redundancy degree, end-to-end delay, and useful throughput ratio, are investigated. The simulation results and performance analysis reveal that how wireless channel quality can influence the performance of WMNs and how different fault-tolerant mechanisms can be efficient and effective for latency-sensitive applications in WMNs. The results can also provide the enlightening insights for efficient design of fault-tolerant routing protocols for many-to-one traffic pattern in WMNs.
