Topology Control with Power and Rate Adaption in Wireless Mesh Networks with QoS Constraint

Kunxiao Zhou, Hui Zhao, and Xing Tang
Abstract—This paper discusses topology control jointing power control problem in wireless mesh networks with QoS guarantee. We are given a set of mesh routers in a plane, some of which are called gateway nodes, as they have wire connection to the Internet. Our task is to construct a routing forest (a set of trees rooted from the gateway nodes), configure the transmission power of each node, such that the constructed network topology can meet the QoS requirement and the system throughput is maximized. We consider rate adaption in this paper. Links can choose an appropriate rate to transmit, according to the channel environments, such as the distance between two end-nodes and the transmission power of the sender. In our proposed method, gateways greedily add routers to its own subtree, in the order of relative distance. A node has a small relative distance to a gateway, if it is closer to this gateway and farther away from all other gateways. In each round, we select the candidate node to be added, and configure transmission power and data transmission rate, such that the QoS requirement is fulfilled and the system total throughput is maximized. Simulation results have shown that our method can significantly improve the network throughput, guaranteeing QoS requirement.

Index Terms—Topology control, power control, rate adaptation, QoS, wireless mesh networks.
