Opportunistic routing (OR) schemes, such as ExOR, have been shown to provide significant throughput gains over traditional best-path routing schemes for wireless networks. Though the performance of OR schemes depend on the bit-rate, they currently use a fixed rate for transmitting packets. While several schemes have been proposed for selecting bit-rate for unicast transmission to a single receiver,...
Finding the optimum path or routing always is an important and difficult issue in a practical dynamic network. In this paper, a new routing approach that due to multiple requirements in the reconfigurable network is briefly discussed. In order to obtain the optimum path between two nodes, we use the ant algorithm with which the problem can be attached to select the path. Simulation results shows that,...
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...
