— The IEEE 802.15.3 medium access control (MAC) protocol is an emerging standard for high bit-rate wireless personal area networks, specifically for supporting high quality multimedia streams. To date there are no published work on the performance of the IEEE 802.15.3 MAC with respect to some of its configurable parameters and there has been no work related(More)
The IEEE 802.15.3 MAC enables high-rate communications between devices in a wireless personal area network and has good support for applications requiring quality of service (QoS). To meet applications' QoS requirements, such as delay and jitter, the channel time allocation (CTA) scheduler plays an important role in sizing and positioning CTAs within each(More)
In this paper, we outline a simple approach, called ROAR, that enables the Ad-Hoc On-Demand Distance Vector (AODV) routing protocol to strengthen its routes by recruiting neighbors of nodes on the least cost path as support nodes during the route construction process, and working closely with the medium access control (MAC) to employ an opportunistic(More)
This paper proposes MiniMesh, an opportunistic transmission mechanism for the IEEE 802.15.3 medium access control (MAC) protocol; a key technology to realizing wireless personal area networks (WPANs). MiniMesh exploits the varying channel conditions to devices in a WPAN, thereby enabling the sender and receiver of a flow to transmit at high data rates when(More)
— This paper describes the development of a real-time digital simulation platform that can be used for the teaching of design principles for power system controls. In the developed approach, a rapid controller-prototyping platform (dSPACE) is interfaced to a real-time power system simulator (RTDS). The real-time platform is very successful when used in a(More)
Mobile ad-hoc networks (MANETs) are dynamic and multi-hop in nature. As nodes continually join and leave the MANET, managing the problem of address conflicts is particularly challenging. In the past, researchers have gone to great lengths to ensure that nodes are assigned unique addresses and various protocols and policies have been designed to resolve(More)
— The proliferation of consumer devices with high processing and storage capabilities has created a tremendous demand for high-speed wireless networking. The IEEE 802.15.3 working group is tasked with developing key technologies to meet these demands and has thus far standardized a new medium access control (MAC) and is working towards standardizing a new(More)
— In sensor networks, the size of the medium access control (MAC) address is prohibitively expensive when one considers the small payload and the cost of transmitting one bit. We address this problem by proposing a technique that encodes L-bits of the payload with a key derived from MAC addresses. We show how the decoding process removes the need for MAC(More)
Interpretation of imagery requires contrast between the object being sought and its background. A technique is described for increasing the contrast of selected objects based on their spectral reflectance or emittance characteristics, and two applications are discussed. Means for implementing this technique with an optical-mechanical scanner, multielement(More)
