Much work has been done on routing in Ad-Hoc networks, but the proposed routing solutions only deal with the best effort data traffic. Connections with Quality of Service (QoS) requirements, such as voice channels with delay and bandwidth constraints, are not supported. The QoS routing has been receiving increasingly intensive attention, but searching for the shortest path with many metrics is an...
QoS routing problem in wireless mesh networks is a NP-complete problem, and it is hard to get the global solution with the traditional algorithm. In this paper, we adopt a novel dynamic ant genetic hybrid algorithm to solve QoS unicast routing problem for wireless mesh network, whose innovation are using the best melting point evaluation strategy to control the calling of the two algorithms dynamically...
Qos anycast is a newly rising network communication service, playing an important role in the area of video stream on-demand. Although the DiffServ network QoS anycast routing architecture is very good, the interleaving services problems exist, which makes its service efficiency decline. A QoS anycast network cluster balancing algorithm based on genetic algorithm and scheduler is introduced in this...
Real-time distributed multimedia applications have special requirements in terms of bandwidth, delay, delay jitter, etc. The current network, essentially being a connection-less network, provides only un-reliable, best-effort service. The data packets may follow different paths to the destination. The network resources, viz., switch buffer and link bandwidth, are fairly shared by packets from different...
Double-layered satellite networks (DLSNs) that consist of low earth orbit (LEO) and medium earth orbit (MEO) satellites are becoming increasingly important since they have higher coverage and better service than single-layered satellite networks. One of the challenges in DLSNs is the development of specialized and efficient routing algorithms. In this paper, virtual topology grouping strategy is improved,...
