This paper examines algorithms to minimize interference in infrastructure wireless mesh networks. A mathematical optimization problem for coloring the active wireless edges in a time-division scheduling frame is formulated. The optimization eliminates primary conflicts and minimizes secondary conflicts. The active wireless edges are specified in an integer zero-one 'edge-specification' matrix. An...
This paper introduces a new method for distributed interference mitigation in full spectral-reuse OFDMA cellular networks. This considers the use of pre-defined frequency-domain power profiles helping make the interference more predictable across the subcarriers. We propose a method for computing the power profiles so as to maximize the capacity of the system in case of maximum throughput scheduling,...
This paper targets the problem of optimum power allocation and link scheduling in cellular systems. In particular, the uplink performance of OFDMA (orthogonal frequency division multiple access) is investigated. By means of heuristic relaxation, the NP-hard problem of joint power control and scheduling is transformed into one of power controlled random access (PCRA), which is formulated as a convex...
