Abstract

Wireless sensor network is a set of many tiny sensor nodes eachof which consists of a microprocessor with sensors and wirelesscommunication device. Because centralized control is hard toachieve in a large scale sensor network, self-* is a key concept todesign such a network. In this paper, as one of self-* properties,we investigate self-stabilization algorithms which is a promisingtheoretical background for wireless sensor network protocols. T.Herman [Procs. International Workshop of Distributed Computing,2003] proposed a transformation scheme of self-stabilizingalgorithm in abstract computational model to sensor network model.However, it is not known that whether expected convergence time oftransformed algorithms is finite or not. We show upper bound ofexpected convergence time of some self-stabilizing algorithms inexplicit formulas.
