Summary form only given. In this talk, we discuss the cross-layer optimization issues in wireless networks by investigating the impact of physical (PHY) layers on the media access control (MAC) and higher protocol layers, or vice versa. In particular, we explore the benefits of cross-layer design for multi-user multi-input multi-output (MU-MIMO) cellular mobile networks, wireless local area networks...
Based on the Hungarian algorithm, the Kuhn-Munkres algorithm can provide the maximum weight bipartite matching for assignment problems. However, it can only solve the single objective optimization problem. In this paper, we formulate the multi-objective optimization (MO) problem for bipartite matching, and propose a modified bipartite matching (MBM) algorithm to approach the Pareto set with a low...
This paper presents a balanced power control scheme for the uplink of cellular MIMO system. The problem of coordinating power consumption reduce with raise in capacity simultaneously is formulated and an efficient algorithm with good performance is derived. Convex optimization method is used to solve the question. In this paper, an adaptive power allocation scheme is proposed by using interior-point...
