Recent research in sensor networks has raised security issues for small embedded devices. Security concerns are motivated by the deployment of a large number of sensory devices in the field. Limitations in processing power, battery life, communication bandwidth and memory constrain the applicability of existing cryptography standards for small embedded(More)

— We consider the problem of determining the positions of wireless nodes using range measurements from multiple , sparsely located, beacon stations with known locations. A large number of such nodes surrounding the beacon stations automatically and cooperatively estimate their position through collaborative efforts and iterative refinements. These positions(More)
