Abstract-In this paper, we address the problem of gateway placement for throughput optimization in multi-hop wireless mesh networks. Assume that each mesh node in the mesh network has a traffic demand. Given the number of gateways need to be deployed (denoted by k) and the interference model in the network, we study where to place exactly k gateways in the mesh network such that the total throughput is maximized while it also ensures a certain fairness among all mesh nodes. We propose a novel grid-based gateway deployment method using a cross-layer throughput optimization. Our proposed method can also be extended to work with multi-channel and multi-radio mesh networks. Simulation result demonstrates that our method can effectively exploit the resources available and perform much better than random and fixed deployment methods.
To improve the throughput, Li et al. REF formulated a throughput optimization considering the number of gateways and interference model.
