To improve the adaptability and stability of Dijkstra algorithm for solving routing problem of service composition, a method to solve routing problem of service composition based on an improved ant colony algorithm is proposed. Firstly, based on the traditional ant colony algorithm, the constraints of it are improved. Secondly, a problem solving model for improved ant colony algorithm is established,...
This paper introduces an approach which aims at improving information access (skills, services) in large networks. A self-organized multiagent analysis of the problem, reducing the number of messages transmitted for a skill search is proposed. The MWAC (Multi-Wireless-Agent Communication) model is extended here to take some specificities of social networks into account, like the information held by...
Mobile ad-hoc networks are one of the most active research areas in the wireless communications field. These networks do not need any fixed infrastructure or configuration, easily adapting to difficult scenarios and types of use. Since mobile nodes are often powered by limited batteries, energy is an important issue in MANETs since the lack of a node can lead to the partitioning of the network. Recently,...
In this paper, we proposed a dual flit transmission rate (DFTR) router architecture according to the property of short distance for the inter-wafer links for 3D Network on Chip (NoC). The equivalent bandwidth of the inter-wafer links can be N times wider than that of the intra-wafer links, since flit transmission rate in vertical direction can be N times fast than that in the horizon direction. Thus,...
It has been widely recognized that the multipath routing can be fundamentally more efficient than the traditional approach of routing along single path. A self-adaptive traffic splitting algorithm, called Dynamic Weighted Round-Robin (DWRR), has been developed to distribute traffic fairly in term of the weight so as to obtain good performance of network load balance. In addition, DWRR can get lower...
In this paper, an adaptive congestion-aware routing algorithm is proposed for mesh network-on-chip (NoC) platforms. Depending on the traffic around the routed node, the proposed routing algorithm provides not only minimum paths but also non-minimum paths for routing packets. Both minimum and non-minimum paths are based on the odd-even turn model to avoid deadlock and livelock problems. The decision...
