The Ad Hoc network is a dynamic topology and self organization network. In allusion to the Ad Hoc network dynamic movement characteristic, present an ant colony Optimization algorithm (ANRBA) for the Ad Hoc network routing based on the network link and node status. In the ANRBA, it uses the load accepted rate, topology variety rate and routing delay time as measurement value to select the routing...
Advances in device technology and dense wavelength division multiplexing have enabled modern optical backbones to provide high data rate services in a cost-effective manner. At the same time, applications are emerging with the potential to leverage these capabilities for short time spans: load migration for Internet clouds, integrated computational grids, and remote surgery. Until such applications...
The fine two-phase routing (F-TPR) scheme, an IP finely-distributed load-balanced routing scheme based on two-phase routing over shortest paths, was previously presented to improve routing performances. F-TPR distributes traffic from a source node to intermediate nodes simply by using IP tunnels. F-TPR provides comparable routing performance to the sophisticated traffic engineering (TE) scheme of...
Channel assignment schemes in Multi-Radio Wireless Mesh Networks (MR-WMNs) usually leave several links sharing the same channel within overlapped transmissions or interference ranges; this is especially true when only one radio is used or when the number of radios is very small compared to the number of orthogonal channels. In order to further improve MR-WMN performance, especially for mobile multimedia...
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...
Fuzzy Control has been a research highlight in network congestion control field. But many existed fuzzy algorithm's parameters and fuzzy rules are static, so it have defect in respond speed, stability and environment sensitivity. As to these problems mentioned above, based on the existed FREM (Fuzzy Random Exponential Marking) algorithm, this thesis explores adaptive FREM algorithm - AFREM (adaptive...
Active queue management (AQM) at routers can effectively control the queue length while keeping high throughput of routers. In this paper, a new AQM algorithm called Hang algorithm based on a modified Smith predictor is proposed. Theoretic analysis and extensive simulation shows that the developed control scheme is effective in dealing with transmission delay and other uncertainties. Comparison with...
In order to improve the speed and efficiency of dynamic route solution for traffic network, the paper constructs parallel simulation solution framework using distributed and parallel simulation technology and illuminates parallel simulation strategy which master process assigns sub-task to slave process. At the same time, the parallel simulation algorithm and implemented process of dynamic route solution...
The aim of this paper is to introduce the implementation of a MAC protocol on a Load-balanced short-path routing algorithm [1], and to show the effect of the MAC requirements on the behavior of the protocol. This work provides an estimate of how might the overhead introduced by the MAC protocol affect the behavior of the routing algorithm, i.e. how it would affect the load on the nodes of the network...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
In this paper, we propose load distribution strategies for divisible loads for networked computing environments where computation and communication resource characteristics are unknown and/or vary with time. The principle on which our strategies are formulated is based on using probing loads to estimate the network characteristics and using them to determine the best possible load distribution. This...
Modern network processor systems require the ability to adapt their processing capabilities at runtime to changes in network traffic. Traditionally, network processor applications have been optimized for a single static workload scenario, but recently several approaches for run-time adaptation have been proposed. Comparing these approaches and developing novel run-time support algorithms is difficult...
