Tone Based MAC Protocol for Use With Adaptive Array Antennas

This paper presents a novel Tone-based 802.11b protocol for use in wireless networks where nodes are equipped with adaptive array antennas. The protocol relies on the ability of the antenna and Angle of Arrival AoA algorithms to identify the direction of transmitters and then beamform appropriately to maximize SINR (Signal...

Implementing a Low Power TDMA Protocol Over 802.11

A wireless network of remotely located, self-powered video sensors must make efficient use of limited network capacity and power. An ideal media-access protocol for such network would fully utilize available throughput while using no more power than necessary and maintaining a reasonable level of fairness. To accomplish these goals, this...

From Chapter Two: The appliance computing culture

The appliance computing culture earned its successes by focusing on the revenue generation side - and that, in turn, drove its own evolution to database technology, the "application as interfaces to data" view, and tight evolutionary links between University research groups and companies like DEC and DG. by Paul Murphy
