Linear interference alignment (LIA) is one of the key interference mitigation techniques to enhance the wireless MIMO network capacity. The generic LIA feasibility amounts to whether or not a well-structured random matrix with entries drawn from a...
Multi-packet reception (MPR) technology provides a means of boosting wireless network capacity without requiring additional spectrum. It has received widespread attention over the past two decades from both industry and academic researchers. Despite...
Fractional Link scheduling is one of the most fundamental problems in wireless networks. The prevailing approach for shortest fractional link scheduling is based on a reduction to the maximum-weighted independent set problem, which itself may not...
Shortest link scheduling (SLS) is one of the most fundamental problems in wireless networks. Almost all of the state-of-the-art approximation algorithms for SLS in wireless networks are resorted to the ellipsoid method for linear programming...
This paper addresses the joint selection and power assignment of a largest number of given links which can communicate successfully at the same time under the physical interference model. For this optimization problem, we present a constant-...
This paper studies the problem of selecting a maximum independent set of links with a fixed monotone and sublinear power assignment under the physical interference model. The best-known approximation bound for this problem is a very large constant....
