To efficiently manage the sensor networks the topology of the entire network has to be discovered by the monitoring node. In this paper a topology discovery algorithm for sensor networks has been described. The algorithm finds a set of distinguished nodes, using whose neighborhood information the approximate topology of the network is constructed. Only these distinguished nodes reply back to the topology...
Ant colony optimization (ACO) is a powerful optimization technique that has been applied to solve a number of complex optimization problems. One such optimization problem is network topology design of distributed local area networks (DLANs). The problem requires simultaneous optimization of a number of objectives, such as monetary cost, average network delay, hop count between communicating nodes,...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
