In wireless mesh networks, joint optimization of routing and link scheduling within a time-division multiplexing approach is commonly sought to provide end users with high data rates. However, the strategies proposed to this end usually proceed by means of complex optimization models, which also often rely on oversimplified assumptions, especially for what concerns wireless interference. In the present...
Wireless interference can make a significant impact on the performance of a wireless network. The paper studies TDMA-based timeslot allocation to schedule links efficiently under RTS/CTS interference model of wireless networks, and presents an efficient centralized timeslot assignment algorithm. In addition, the paper presents an effective heuristic algorithm for calculating end-to-end bandwidth on...
In this paper, we study QoS routing in wireless mesh networks with cognitive radios, which involves route selection, channel allocation and scheduling. It turns out to be a hard problem because of the impact of interference and channel heterogeneity. We formally model it as an optimization problem and present an integer linear programming (ILP) formulation to provide optimal solutions. We then present...
