Topology Control (TC) is a well known technique used in wireless ad hoc and sensor networks to reduce energy consumption. This technique coordinates the decisions of network nodes about their transmission power to save energy, prolong network lifetime, and mitigate MAC-level medium contention, while maintaining network connectivity. In order to ease the implementation and the study in systematic way...
Epidemic-based communications, or 'gossiping', provides a robust and scalable method for maintaining a knowledge base in a sensor network faced with an unpredictable network environment. Since sensed information is often periodic in time, protocols should be able to manage multiple messages in an efficient way. We describe a mathematical model of gossiping dealing with multiple messages. We present...
Distributed topology control protocols (DTCP) for wireless sensor networks (WSN) coordinate nodespsila decisions regarding their transmission ranges, in order to set up a network with a certain connectivity, while reducing nodespsila energy consumption and/or increasing network capacity. The key issue in DTCP is to choose the most suitable transmission power level (TPL) among those available for each...
