On Improving the Reliability of Packet Delivery in Dense Wireless Sensor Networks
—Wireless sensor networks (WSN) built using current Berkeley Mica motes exhibit low reliability for packet delivery. There is anecdotal evidence of poor packet delivery rates fro...

Packet level scheduling schemes for multi-user MIMO systems with beamforming
We investigate the packet-level scheduling for the downlink of multiple-input multiple-output (MIMO) multi-user systems using beamforming. We consider the traffic arrival process ...

Robust Cooperative Relaying in a Wireless LAN: Cross-Layer Design and Performance Analysis
—A key technology in cooperative communications is distributed space-time coding (DSTC) which achieves spatial diversity gain from multiple relays. A novel DSTC, called randomize...

Self-interference in Multi-hop Wireless Chains: Geometric Analysis and Performance Study
Abstract. In the presence of interference, two single hop links can interact in a number of different ways, exhibiting significantly different behavior. In this paper, we consid...

Detecting spatial congestion in multihop wireless networks
While TCP is highly successful in the wire-line Internet, its performance fast degrades as the number of hops increases in multihop wireless networks. It is due to not only the ha...
