This paper introduces a MAC protocol MORIF (Modified Response and Immediate Forwarding) for the full-duplex star network, which consists of coordinators and end nodes. The protocol defines the routing, advanced requesting and immediately forwarding mechanisms, which help a lot in solving the existing important problems, such as hidden terminal, congestion and high end-to-end delays. By modeling wi... View full abstract»

In this paper, we investigate a low complexity power allocation and relay-jammer selection in a distributed wireless secure networks model with one source, one eavesdropper, one destination and multiple friendly intermediate nodes. A two-phase cooperative jamming scheme is proposed, in which one decode-and-Forward (DF) relay and one or two jammers are selected from the intermediate nodes to enhanc... View full abstract»

The SIP(Session Initiation Protocol) is the core control protocol of the Next Generation Networks(NGN), which is used for initiating, modifying and tearing down multimedia sessions on IP data network. Because the SIP server is the core facility of NGN, its realization is especially important. One way to realize the SIP server is the proxy server, which mainly provides routing service. Namely, it e... View full abstract»

In this paper, we design an architecture to implement a QoS system based on OpenFlow. The system can filter malicious packets that have no permission to gain quality of service, and can guarantee scheduling the fastest path for QoS packets in working network. By predicting and estimating current network flows, we implement to assign optimal path for QoS flow without affecting the rest of the norma... View full abstract»

This paper first introduces the basic principle of IEEE 802.11 DCF and analyses the effect of the two system parameters, network size and minimize contention window, on the performance in terms of saturation throughput and probability of collisions. To overcome the shortcomings of the original 802.11DCF, the influence of the contention window's size was analyzed. 802.11DCF-SD (Success Decrease) me... View full abstract»

To solve the congestion of NoC caused by overload such as injection rate increase, this paper proposes a novel routing algorithm, that is Dynamic and Mixed Routing(MIXROUT) which is based on XY Routing(XY) and Multiple and Load-Balance Path Routing(MULTI).
