Interferer Nulling Based on Neighborhood Communication Patternsterns can also be modified to have very small gains in the direction of interference and noise sources (nulling). In this paper we propose nulling algorithms based on the long-term communication patterns and routing tables in ad hoc networks. Simulation results show that this approach considerably i

On the Beneficial Effects of Cooperative Wireless Peer-to-Peer Networkingmmunications. The major problems in conventional cellular communication systems are the limited autonomy of battery-powered mobile devices and the low data rate of currently available services. In this chapter a viable solution is presented to overcome the aforementioned limitations by proposing the

Fundamental Bound on the Capacity of Ad Hoc Networks with Conventional Hop-by-Hop Routingf such networks with conventional hop-by-hop routing. One of these bounds is based on fundamental information theory, but applied to switching systems instead of transmission systems. This bound scales well with network size. The second bound, based on more traditional network flow optimization, is

The security of the key management solution should not impede mobility of devices by adding undue delays. Thus, secure and fast key management during mobility

Enhanced Operation Modes in IEEE 802.16 and Integration with Optical MANsnology progresses, wirelessly connected users may now exploit a bandwidth comparable to the one provided by copper-based access technologies (e.g., xDSL). WiMAX (i.e., IEEE 802.16) is one of the wireless technologies with such potential..This paper addresses IEEE 802.16 aspects, from the enhanced mo

WPAN Applications and System Performance PAN). The millimeter-wave WPAN system is supposed to transmit 2 Gbps or more as mandatory mode.We propose “Single carrier approach” which will offer easily high data rate and provide “Kiosk file downloading” application more efficiently. Computer simulation results on the proposed systems show exce
