For MAC (Media Access Control) protocol not providing QoS(Quality of Service) guarantees. With the increase of multimedia sevices in wireless networks(for example:voice, video, etc), when the networks get crowded, real-time applications will decrease its performance. We proposed a wireless network algorithm for 802.11e, witch supports fixed nodes and mobile nodes, and also swiches and new connections...
Infrastructure meshed networks provide access to wireless clients that do not participate in traffic forwarding. This paper proposes minimalist instant handoff for wireless access networks (MIHAN), allowing for seamless movement of nodes in coverage areas, while maintaining connectivity. The approach of MIHAN is that all client frames, send in radio range of an access node, are received and forwarded...
TCP was designed to perform on wired networks, where packet loss is mostly caused by congestion, as compared to wireless networks, where losses due to error in channel are more likely. Hence TCP respond to all kind of losses by invoking congestion control and avoidance schemes resulting in performance degradation. Several solutions for the improvement of TCP over wireless link have been proposed which...
In this paper we present a solution for providing a fast handover in wireless networks which involve network access control based on the ExtensibleAuthenticationProtocol. We propose an approach based on cryptographically generated identities, which reduces the number of round trips during authentication phase and achieves the objective of reducing the impact on existing EAP deployments.
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
