Adaptive radio resource management in a sectored cell for broadband wireless access systems
(2010)
In this work, we analyze the performance of a multi-user sectored MIMO/OFDMA system under the limited feedback constraint. Dynamic radio resource management methods are used to a reuse-one sectorized cell in order to reduce ...
Spatial multiplexing based on distributed antenna arrays for mobile WiMAX networks
(2010)
A novel cell architecture based on Distributed Antenna Arrays for next generation mobile WiMAX systems is proposed. By exploiting Spatial Multiplexing and beamforming techniques, our target is to maximize the throughput ...
Mobility support through caching in content-based publish/subscribe networks
(2010)
In a publish/subscribe (pub/sub) network, message delivery is guaranteed for all connected subscribers at publish time. However, in a dynamic mobile scenario where users join and leave the network, it is important that ...
Storing and replication in topic-based publish/subscribe networks
(2010)
In current publish/subscribe networks messages are not stored and only active subscribers receive published messages. However, in a dynamic scenario a user may be interested in content published before the subscription ...
Quantifying the overhead due to routing probes in multi-rate WMNs
(2010)
The selection of high-throughput routes is a key element towards improving the performance of wireless multihop networks. While several routing metrics have been proposed in the literature, it has been shown that link-quality ...
Reputation-based internet sharing in wireless neighborhood community networks
(2010)
This paper proposes easily applicable distributed reputation-based policies to motivate users of a wireless community to share their Internet connection in a p2p fashion. The goal is the provision of free and good quality ...
Social Network Analysis Concepts in the Design of Wireless Ad Hoc Network Protocols
(2010)
This article presents a survey of ad hoc networking protocols that have used concepts such as centrality metrics and community formation from the area of social network analysis, which is seen as a network measurement task ...
New channel allocation techniques for power efficient WiFi networks
(2010)
Energy efficiency becomes evergreen than ever before. Over the last few years a significant research in wireless communications, aiming to enhance communications efficiency subject to constraint of power consumption, has ...
Optimal Transmission Rate Control Policies in a Wireless Link Under Partial State Information
(2010)
We consider the problem of PHY layer transmission rate control for maximum throughput on a wireless link over a finite time horizon. For each link state there exists a most advantageous transmission rate for the controller. ...
Control of Wireless Networks with Rechargeable Batteries
(2010)
We consider the problem of cross-layer resource allocation for wireless networks operating with rechargeable batteries under general arrival, channel state and recharge processes. The objective is to maximize total system ...
