A wave-channel balanced dynamic RWA algorithm presented in this paper based on the business for electric power optical transport network. This algorithm is designed to solve the routing and wavelength assignment problems of multibusiness request in the complex power optical transport network. This algorithm made the classification of business requests and set the priority of each request according...
Due to the explosive growth of multimedia content (especially videos) over the Internet, content-centric networking (CCN) is proposed to remit the problems of modern bandwidth-intensive Internet usage patterns. Additionally, the current streaming media coding is designed for video service for IP networks. However, there are few researches who concentrate on efficient streaming media coding for the...
Underwater acoustic wireless sensor network (UAWSN) is the result of global popularity of networks which combines underwater acoustic communication, networks, modern signal processing, sensor techniques and so on. Because of the particular characters of UAWSN such as big transportation delay, limited node power supply, many of the mature WSN techniques can't be implanted to UAWSN directly. UW-CSMA/CA...
Forwarding system is one of key components for high-performance router. In this paper, the architecture of router is described first. Then, software system of centralized router and the process of a packet are analyzed. At the end, the performance bottleneck of centralized router is pointed out. To get better performance, we propose a fast-forwarding mechanism to increase the speed of packet, which...
This paper proposed a topology clustering scheme based on genetic algorithm (GACluster) to improve the topology clustering performance in the course of constructing the hierarchical overlay multicast. The scheme firstly constructed the clustering feature space by normalizing the two routing metrics (overlay path delay and overlay node access bandwidth), and then implemented genetic algorithm for the...
This paper compared the clustering performance of the proposed FCM-based clustering scheme with HCM to the hierarchical topology optimization in overlay multicast. The paper firstly depicts the proposed scheme including 1) defining the clustering feature distance based on overlay path latency, 2) calculating the Euclidean distance within each pair of overlay nodes to construct the fuzzy membership...
The routing topology optimization is one focus of overlay multicast research. To improve the routing scalability issue, this paper proposed an improved multicast routing protocol based on fuzzy clustering (FHRouting) to construct a hierarchical topology tree for the routing optimization in overlay network. The scheme firstly formulated the issue as a degree-restraint minimal latency optimization and...
MAODV is widely accepted as an on-demand multicast routing protocol for mobile ad hoc network (MANET). This paper presents a hybrid zone based multicast routing scheme (HZMAODV) to solve the scalability and robustness issues of MAODV. Inspired by the zone division principle and the geography aware routing, the proposed scheme firstly divides the routing area into several zones based on geographic...
This paper proposed a dynamic fuzzy clustering scheme with adaptive fuzzy threshold to the hierarchical topology optimization in overlay multicast. The scheme firstly normalized the two routing metrics - overlay path delay and overlay node access bandwidth-- to comprise the clustering feature vector, and then calculated the Euclidean distance within each pair of overlay nodes to construct the fuzzy...
To solve the topology cluster detection in the multicast routing optimization, this paper proposed a weighted fuzzy clustering algorithm for the mixed data set indicating two different routing metrics. The scheme first normalized the related routing metrics to comprise the feature vector, and then weighted the features in the fuzzy membership matrix corresponding to their related importance to the...
