A Low-Complexity Intrusion Detection Algorithm For Surveillance Using PIR Sensors In A Wireless Sensor Network
(2011-07-12)
A Wireless Sensor Network (WSN) is a dense network of autonomous devices (or motes) with sensors that cooperatively monitor some physical or environmental conditions. These devices are resource constrained -limited memory, ...
Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)
We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ...

Energy-Efficient Data Fusion Techniques for Wireless Sensor Networks
Wireless sensor networks (WSNs) are finding increasing use in applications such as environmental monitoring, military surveillance, and healthcare due to their low cost and ease of deployment. However, the nodes in a ...
Modeling, Performance Analysis and Design of Wireless Networks for Embedded Sensing Applications
The general theme of this thesis is modeling, performance analysis, and design of wireless networks under standardized CSMA/CA MAC protocols. In particular, we consider two widely used MAC protocols, namely, IEEE 802.15.4, ...
Role of Power Control in Enhancing the Performance of Opportunistic Selection Schemes
Opportunistic selection reaps the benefits of multiuser diversity in many wireless
applications. For example, it increases throughput of cellular networks, lifetime
of wireless sensor networks, and improves diversity in ...
