WSN03-5: Load-balancing and Inter-domain Mobility for Wireless Mesh Networks

This paper proposes a scheme for domain partition to achieve the tradeoff between load-balancing and inter-domain mobility to reduce the negative impact of the host mobility. The load-balancing scheme for domains includes: an initialization procedure to divide a mesh network into domains, and a load adjustment procedure to rebalance the traffic load of neighboring domains when required. Moreover, the proposed scheme provides inter-domain mobility in support of multi-hop communication with the multi-hop cellular IP (MCIP) mobility protocol. Our experimental results show that the proposed protocol effectively controls the migration of mesh routers as well as mobile stations.
