A fast clustering routing algorithm based on ant colony optimization and Dijkstra Algorithm is proposed on account of the router-level network topology simulation. First, FCRSA takes advantages of ant colony optimization to cluster the nodes in the network, then uses the improved Dijkstra algorithm to search for the shortest paths in the clusters, reducing the time needed for path selecting in router-level...
A routing computation strategy based on improved clustering algorithm is proposed in this paper. It uses a clustering algorithm based on K-means and Dijkstra (CAKD) in topology partitioning. The routing information of each node can be computed during the clustering process, and CAKD reduces the time cost in routing computation and the storage in storing routing information. Experiments showed that,...
This paper first introduces existing congestion control algorithms and analyses their weakness. And after discusses the features and requirements of network topology simulation system, a congestion control scheme based on improved RED algorithm named DFCC was presented. DFCC reduces the package loss by adjusting link delay dynamically when congestion happens. And by means of twice optimization of...
We propose a new tool, named DSGen, a distributed synthetic network traffic generation system. It is designed for network experimental in off-line environments. Since the experimental environment has some detective points compared with on-line one in the context of network background traffic and contention for servers' resource with other real users, a complementary approach that designs a system...
Analyzed the features of router-level topology simulation, and proposed an algorithm HRSA facing router-level network topology simulation based on Dijkstra algorithm aiming at actual Internet stratified topology structure. By the way of adding the shortest routing table on the core router, the time of searching the shortest path in router-level topology simulation has been reduced effectively. The...
