Automated advance reservation has the potential to ensure a good scheduling solution in computational Grids. To improve global throughput of Grid system and enhance resource utilization, workload has to be distributed among the resources of the Grid evenly. This paper discusses the problem of load distribution and resource utilization in heterogeneous Grids in advance reservation environment. W...

Fat-tree networks have been widely adopted to High Performance Computing (HPC) clusters and to Data Center Networks (DCN). These parallel systems usually have a large number of servers and hosts, which generate large volumes of highly-volatile traffic. Thus, distributed load-balancing routing design becomes critical to achieve high bandwidth utilization, and low-latency packet delivery. Existin...

Load balancing is a primary consideration in Adhoc networks, due to scarcity of resources. Equitable distribution of the load reduces consumption of network resources and provides homogeneous traffic characteristics in the network, such as load per node or the time from end-to-end incurred on each path. In this paper we present an optimization of the reactive routing protocol AODV with load bal...

To solve the problem that traffic network of rapid change is easy to fall into the situation of network congestion, based on the network load information, we use the average transmission time and local interface queue length information to find the path of the load balancing, and select minimum load channel through load-aware channel allocation. Considering interference suppression, load balanc...

This paper proposed and evaluates a QOS routing policy in packets topology and irregular traffic of communications network called K-shortest Widest paths Q-Routing. The technique used for the evaluation signals of reinforcement is Q-learning. Compared to standard Q-Routing, the exploration of paths is limited to K best non loop paths in term of hops number (number of routers in a path) leading ...

By spreading the workload across a sensor network, load balancing reduces hot spots in the sensor network and increases the energy lifetime of the sensor network. In this paper, we design a node-centric algorithm that constructs a loadbalanced tree in sensor networks of asymmetric architecture. We utilize a Chebyshev Sum metric to evaluate via simulation the balance of the routing trees produce...

in this study, an extended stress-based forming limit diagram (fld) for prediction of necking based on the marciniak and kucznski (m-k) model is represented and applied in tube hydroforming. the bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. this adaptive simulation technique is based on the ability to detect the onset and g...
