Abstract:

Wireless sensor-actor networks are a recent development of wireless networks where both ordinary sensor nodes and more sophisticated and powerful nodes, called actors, are present. The role of the actors is to take various decisions, relevant for the network, based on the data retrieved and transmitted by the sensors. In order to fulfill their role, actor nodes, independently of the sensor nodes, coordinate with each other via their own communication links. However, when an actor node fails, it may hinder the overall actor coordination. Hence, some backup mechanisms need to be enforced. In this paper we present a novel method on how to always enforce a reconstruction of the failed coordination links among the remaining active actors in a manner that aims to achieve various optimality properties. We argue that our method promotes a reusable coordination model of employing existing infrastructure as a fault-tolerance mechanism. Moreover, various forms of the coordination links are emphasized.
