The current IEEE 1609.4 standard defines multi-channel operations to alternate control and
service channel intervals during a period of 100ms. However, there is no mention of service …

The application of directional antennas in wireless ad hoc networks offers numerous
benefits, such as the extended communication range, the increased spatial reuse, the …

In the context of ad hoc networks, use of directional antenna can largely reduce the radio
interference, thereby improving the utilization of wireless medium and consequently the …

Computer networks are complex constructs consisting of many entities that simultaneously
interact with one another. Understanding various aspects of such complex systems and their …

This paper investigates the channel allocation problem in multi-channel wireless networks
with directional antennas. In particular, we propose a general analytical framework on the …

This dissertation addresses the problems of capacity and lifetime of Wireless Multimedia
Sensor Networks (WMSNs). More specifically, it focuses on low-cost WMSNs, powered by …

This paper analyzes the impact of directional antennas in improving the transmission
capacity, defined as the maximum allowable spatial node density of successful …

In recent years, multimedia wireless transmissions have become a rapidly growing field and
have received increasing attentions. Enabling multimedia communications over wireless …

In an ad hoc network, security is a serious issue since the channel is open and there is no
central administrator. Recent years, in an ad hoc network, the eavesdropping attack, which …
