A MIMO network is a wireless network made up of individual MIMO links. The problem we consider is to maximize throughput in a multihop MIMO network with interference suppression. Our problem formulation accounts for variable rates on the MIMO links, which depend on the channel conditions of the link, and the manner in which the diversity-multiplexing… (More)

The problem that we consider is that of maximizing throughput in a MIMO network while accounting for variable rate streams on MIMO links. The stream rates on a link depend on the channel conditions of the link, and the manner in which the diversity-multiplexing tradeoff is handled. In this work, we use the dependence of stream rates on the channel to… (More)

We tackle the problem of determining the beamforming and combining weights in a network of interfering multiple-input multiple-output (MIMO) links. We classify any strategy for computing these weights as either unilateral or bilateral. A unilateral strategy is one for which the responsibility of cancelling interference from one node to another is… (More)

We propose an algorithm to allocate streams and find the corresponding beamforming and combining weights that maximize the sum rate of a set of interfering multipleinput multiple-output (MIMO) links. Our algorithm iteratively computes the beamforming and combining weights of each link and determines how many streams, if any, are allocated to each link.… (More)

Wireless networks have quickly become part of everyday life. Wireless LANs, cell phone networks, and personal area networks are just a few examples of widely used wireless networks. However, wireless devices are range and data rate limited. The research community has spent a great deal of effort on finding ways to overcome these limitations. One method is… (More)

In this report, the problem of interference in dense wireless network deployments is addressed. Two example scenarios are: 1) overlapping basic service sets (OBSSes) in wireless LAN deployments, and 2) interference among close-by femtocells. The proposed approach is to exploit the interference cancellation and spatial multiplexing capabilities of… (More)

We propose an algorithm whose goal is to maximize the sum rate of a set of interfering multiple-input multiple-output (MIMO) links by jointly optimizing which subset of transmitters should transmit, the number of streams for each transmitter (if any), and the beamforming and combining weights that support those streams. We present numerical results to… (More)

This paper addresses the problem of fair scheduling of MIMO links in dense wireless network deployments where interference suppression is carried out via linear MIMO processing to optimize network performance. We formulate and solve an optimal MIMO link scheduling problem, where the goal is to maximize aggregate throughput while meeting a specified fairness… (More)

The report details implementation of the infrastructure based wireless mesh networks, certain existing routing strategies and performance analysis of different topologies. The backbone of the network consists of a gateway, an access point, two routers and a client. The bandwidth obtained at these different nodes for different topologies were extensively… (More)
