The increased usage of directional methods of communications has prompted research into
leveraging directionality in every layer of the network stack. In this paper, we explore the use …

A mobile ad hoc network (MANET) is defined as an autonomous system of mobile routers
(and their associated hosts) connected by wireless links. the union of which forms an …

We analyze the DEC fuzzy time technique (Hu [HU]) for both a single computer system and a
network of hosts. Specifically, we investigate covert channels in a model of a fuzzy time …

Medium access control (MAC) protocols simultaneously integrating transmission power (TP)
control with directional antennas have the potential to enhance both energy savings and …

RF based communication technologies have been the crux of wireless networking. The
limitation of radio frequency (RF) based network is that the throughput deteriorates as new …

Beamforming is regarded as a key element for multiantenna ad hoc networks. However, it
cannot simultaneously provide the omnidirectional and long-range coverage required by …

We define a node to be “captured” when its receiver is engaged in receiving a packet that is
not intended for that node. A unicast transmission using IEEE 802.11, although intended for …

Recently, free space optical sensor networks (FSOSNs), which are based on free space
optics (FSO) instead of radio frequency (RF), have gained increasing visibility over …

Directional antennas have the potential to provide a fundamental breakthrough in ad hoc
network capacity. Omni-directional nature of transmission restricts the network capacity …
