WIMAX (Worldwide Interoperability for Microwave Access) is a promising new networking technology that potentially offers high speed and wide area wireless access services that complement consistently the 3G and WiFi access networks capabilities. The standard proposes an adaptive modulation scheme which allows WiMax nodes to communicate from various modulation coding schemes according to the link quality...
This paper addressed three issues in the context of 802.11, which are important but somewhat ignored in the current research. We then give a brief description of our cross layer based solutions which entails no change in the 802.11 standard. The preliminary measurements show a significant improvement on the wireless transmission efficiency, our future work will focus on the real deployment while taking...
The threshold protocol based on polynomial needs shuffling scheme to share the secret securely. For avoiding the complexity on communication and operation of the complete-shuffling scheme, this scheme applies brief shuffling algorithm. This paper introduces random order sequence via the dynamic attribute of the feedback time and presents a partial-shuffling scheme. In order to defense the adversary...
The features of mobility, which enormously impact on how communication is evolving into the future, represent a particular challenge in todaypsilas wireless networking research. After an identification and evaluation of the gap between the discontinuities of the communication service inherent to the physical layer of mobile networks and the continuity requirements issue from the stream centric multimedia...
Based on an identification and evaluation of the subtle counterproductive interactions between the WLANs MAC layer and the transport layer, this paper shows a new approach towards congestion control for WLANs. We introduce a specialization of TFRC (MTFRC: mobile TFRC), which is adapted to wireless access networks. This TFRC specialization requires only slight changes to the standard TFRC protocol...
Resource discovery is very critical in mobile computing technology. With wireless grid technology advances, an increasing number of resources, how to find the necessary resources accurately and efficiently for users in a large mobile grid environment, has become a problem has to be solved in grid technology. In this article, we mix the two distributed technology mobile grid and mobile agent together,...
