Access-enhanced hybrid routing protocol for hybrid wireless mesh network

摘要

Because of the feature of hybrid wireless mesh network, hybrid routing protocol is the most proper routing protocol for this kind of network. Hybrid routing protocol is composed of proactive routing protocol and reactive routing protocol. The proactive one is adaptive for static mesh routers, and the reactive one is suitable for mobile mesh clients. Existing hybrid routing protocols all neglect the access process. That is, if the nearest access mesh router knows the way to destination, it will be used to provide service for the mesh clients unconditionally, which will cause congestion of this access mesh router and load of the whole proactive route. This paper proposes an access-enhanced hybrid routing protocol to improve the situation. During the process of access, the condition of the whole proactive path containing the access mesh router will be considered. The mesh router whose proactive path condition is better will reply the request from mesh clients. According to the simulation results, this access-enhanced hybrid routing protocol can get better network performance.
