Knorn, F. and Stanojević, R. and Corless, M. and Shorten, R. (2009) A framework for decentralised feedback connectivity control with application to sensor networks. International Journal of Control, 82 (11). pp. 2094-2114. ISSN 1366-5820
In this paper we propose a decentralised algorithm for connectivity maintenance in a distributed sensor network. Our algorithm uses the dynamics of a consensus algorithm to estimate the connectivity of a network topology in a decentralised manner. These estimates are then used to inform a decentralised control algorithm that regulates the network connectivity to some desired level. Under certain realistic assumptions we show the closed loop dynamics can be described as a consensus algorithm with an input, and eventually reduces to a scalar system. Bounds are given to ensure the stability of the algorithm and examples are given to illustrate the efficacy of the proposed algorithm.
