IEEE 802.16 (WiMAX) and IEEE 802.11 (WiFi) are different wireless access technologies with the former being used in Metropolitan Area Networks and the latter used in Local Area Networks. With the increase in popularity of WiMAX and WiFi networks, it is expected that mobile devices in future will be equipped with these radios for data access. Such a scenario presents us with an opportunity to utilize...
Self-Organization refers to the process through which a system changes its internal organization to adapt to changes in its goals & the environment, without explicit external control. The self-organizing capability seen in many natural and artificial systems is closely congruent to the emergent collective intelligence in distributed multi-agent systems. A group of agents interacting locally may...
This paper deals with a problem on edge-colored graphs. The aim is to find a minimum reload cost spanning tree using Ant Colony Optimization (ACO) approach. Given an edge-colored graph, reload costs arise at nodes and depend on the pair of colors on the edges used in traversal through that node. The problem finds practical applications in several domains viz. telecommunication, energy, transportation...
Incipient fault diagnosis of a power transformer is greatly influenced by the condition assessment of its insulation system specifically oil/paper insulation. In recent times, a number of intelligent methods based on AI techniques, Artificial Neural Network and Fuzzy Logic have been used to predict incipient faults in a power transformer based on its insulation studies under various kinds of stresses...
