| Research Abstract |
A wireless mesh communication network can be composed of a large number of wireless routers or wireless devices like sensors, and the traffic from the wireless devices (nodes) to the other network via the gateway and the traffic for managing the wireless devices' positions may overwhelm the network. In this research, we propose to group the neighboring nodes into clusters and furthermore construct them into a hierarchical topology, and propose mechanisms to increase the network throughput, balance the message processing loads among the nodes, and equalize the resource utilization among the nodes.
