Node or link failures and users' mobility are common in trusted network. A QoS (Quality of Service) rerouting mechanism based on vaccination immune genetic optimization is proposed to recover from such failures. The main idea behind this rerouting mechanism lies in maximizing the users' QoS and trusted requirements and the link reuse ratio of the original connection. This paper presents a network...
In this paper, a QoS (Quality of Service) unicast routing and wavelength assignment scheme in IP/DWDM (Dense Wavelength Division Multiplexing) optical Internet is proposed. To solve the routing problem and wavelength assignment, MEA (Multi-Agent Evolutionary Algorithm) and JFF (Joint First Fit) are used in the scheme. To realize the goal of achieving or approaching the Pareto optimum under Nash equilibrium...
Due to the heterogeneity, mobility, instability and other features of NGI (Next Generation Internet), it is difficult to provide users with QoS (Quality of Service). And fault-tolerance needs to be improved in NGI. Thus, an intelligent fault-tolerant QoS unicast routing mechanism based on the outlook algorithm is proposed. The knowledge of fuzzy mathematics and probability theory is introduced to...
In this paper, a QoS handoff decision scheme with ABC (always best connected) supported is proposed, and an optimal handoff solution of assigning N terminals to M access networks is found based on niche PSO algorithm. With help of gaming analysis, Pareto optimum under Nash equilibrium of user utility and network provider utility is achieved or approached for the found solution.
