Non-root-based Hybrid Wireless Mesh Protocol for Wireless Mesh Networks
Wireless Mesh Networks (WMNs) are wireless networks that are composed of mesh routers and mesh clients. Mesh routers have minimal mobility and form the backbone of WMNs. IEEE 802.11s-based WMNs have a default routing protocol, namely, a Hybrid Wireless Mesh Protocol (HWMP). In tree-based proactive mode, HWMP is completely centralized and constrained by the root node, which causes a bottleneck at the root node. In reactive mode, HWMP always initiates path discovery message broadcasting, which uses unnecessary power resources.
