An Overview of Wireless Data Communications
An Overview of Wireless Data Communications(networking)
Selecting the appropriate wireless data communication solution for connecting low-bandwidth electronic devices requires several considerations. These considerations may include range related issues, power requirements, 900 MHz versus 2.4 GHz transmission bands, interference immunity and time-to-market issues.

Locating Internet Routing Instabilities
This paper presents a methodology for identifying the autonomous
system (or systems) responsible when a routing change is observed
and propagated by BGP. The origin of such a routing instability is
deduced by examining and correlating BGP updates for many pre-
?xes gathered at many observation points. routers

Cooperative Diversity in Wireless Networks
in wireless networks,
this dissertation develops energy-efficient algorithms that employ certain kinds of cooper-
ation among terminals, and illustrates how one might incorporate these algorithms into
various network architectures. In these techniques, sets of terminals relay signals for each
other to create a virtual antenna array, trading off the costs—in power, bandwidth, and
complexity—for the greater [...]
Understanding the Basic Networking Functions, Components,
and Signaling Protocols in VoIP Networks
Although voice over IP (VoIP) has existed for several years, it has only recently begun to take off as a viable alternative to traditional voice systems and public switched telephone networks (PSTN). Interest in VoIP has grown in part because the technology can help both [...]
