Regional condition-aware hybrid routing protocol for hybrid wireless mesh network

Abstract

A proper routing protocol can improve the performance of whole network dramatically. Due to the character of hybrid wireless mesh network, hybrid routing protocol combining both proactive and reactive routing protocols suits hybrid wireless mesh network well. However, existing research of hybrid routing protocol is quite few, and mesh routers may be used unreasonably during the process of mesh clients accessing mesh routers. Besides, the condition of whole path and regional condition of mesh nodes is neglected. This paper proposes a regional condition-aware hybrid routing protocol (RCA-HRP). In RCA-HRP, regional conditions of mesh routers and mesh clients are considered respectively. Furthermore, the state of whole proactive path is taken into account to make the access process more effective, and gateway- and client-oriented traffic is taken into consideration comprehensively. The simulation results by ns-3 show the strengths of RCA-HRP in terms of average throughput, latency, and packet loss rate.
