This thesis proposes and analyzes data fusion algorithms that operate on the physical layer of a wireless sensor network, in the context of three applications of cognitive radios: 1. Cooperative spectrum sensing via binary ...

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, ...

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 ...
