Proposal of an Initial Route Establishment Method in Wireless Mesh Networks

Hybrid wireless mesh protocol (HWMP) is consists of on demand routing protocol RM-AODV and pro-active routing based on tree-base routing. When a mesh portal exists as a gateway of a wireless mesh network, tree-based routing is very efficient in fixed mesh deployments. However, with the distance vector routing method, all mesh points need route metrics based on the network topology and many packets are consumed to build the topology. To solve these problems, we define a new address space based on the link state and propose an initial route establishment method with greedy forwarding by using addresses as positional information. From simulations results, we confirmed that the proposed routing method can build the routing topology before the entire wireless mesh network is constructed and reduce the number of control packets for routing, and it also has scalability.
