In this paper, we consider the robust resource allocation problem targeting for providing end-to-end rate guarantee in multi-hop multi-radio multi-channel wireless mesh networks. We incorporate the concepts of interference margin and outage probability to characterize the network robustness under homogeneous and heterogeneous wireless channel conditions. The robust resource allocation problems are...
In this paper, we propose a link outage probability based resource allocation scheme for multi-radio multi-channel wireless mesh networks. The objective is to optimize the link outage probability under the effect of channel variation and external interference while preserving the end-to-end traffic demand requirements. The problem is formulated as a mixed-integer nonlinear programming problem, which...
In this paper, we consider the robust resource provisioning problem targeting for end-to-end rate guarantee under moderate channel variations and external interference. We formulate the robustness optimization problem that explicitly takes into account practical radio switching, co-channel contention, and multi-path routing and traffic splitting constraints. By exploiting the special property of the...
Wireless channels are inherently time-varying due to many different factors, such as fading, shadowing, multipath effects, etc. In practice, it is too complicated to completely capture these factors in a single theoretical framework. Therefore, many simplified channel models have been proposed and widely used in theoretical analysis, protocol design and performance evaluation. However, recent studies...
