We investigate WiMAX mesh networks in terms of delay and throughput trade-off. For a given topology, using our proposed analytical model we study how slot allocation policy and forwarding probability affects per-node and network performance.
Two iterative cross layer schemes are introduced for throughput maximization in multi channel WMN's where each link has a single designated channel. For both schemes, a two phase algorithm is developed where each phase is composed of routing and channel assignment steps. Results extracted from the channel assignment carried out in the first phase are fed back into phase 2 and appropriately utilized...
We propose two algorithms to enhance the throughput of multi-channel WMNs. Towards this goal, we first utilize an iterative algorithm for cases where each link is allowed to be active on a single channel for the whole duration of network operation. To this end, a two phase algorithm with each phase containing an LP formulation step for link flow determination and a channel assignment step is proposed...
In this paper, novel routing tree construction algorithms for emerging multi-channel WiMax networks are presented. Both centralized and distributed schemes are explored. Simulation results show the improvement achieved compared to similar networks with a mesh topology.
