— Ultra-wideband (UWB) technology is expected to provide high data rate services for future wireless personal area networks (WPANs). The WiMedia Alliance recently has launched it...
—In this paper we present APOS, a method for dynamically adapting the parameters of IEEE 802.11g to the estimated system state, with the aim of enhancing the quality of a voice c...
—The IEEE 802.16 standard, or WiMAX, has emerged as one of the strongest contenders for broadband wireless access technology. In our previous work, we proposed a protocol using r...
—Underwater acoustic channel usually has low data rate, long propagation delay, severe multipath effect, and time varying fading. Cooperative transmission is a new wireless commu...
—One of the major threats to cyber security is the Distributed Denial-of-Service (DDoS) attack. In our previous projects, PacketScore, ALPi, and other statistical filtering-based...
—For the sake of maximizing the network lifetime, we propose a novel placement scheme for mobile data collectors in Underwater Acoustic Sensor Networks (UASNs). Our scheme is bas...
— In large Wireless Sensor Networks (WSNs), each hop might incur varying delays due to medium access contention, transmission and computation delays. Fast and efficient query re...

— Directional antennas in multihop wireless networks offer a potential increase in the spatial reuse of the wireless channel. However, existing directional MAC protocols are not ...
Abstract—Proportional Fair (PF) is a frequently used channelaware scheduling algorithm in 3G wireless networks. However, recent work by us and others has shown that, in practice,...
—This work combines two existing defenses against distributed denial-of-service (DDoS) attacks DefCOM and Speak-up resulting in a synergistic improvement. DefCOM defense organize...
