Energy-Driven Reconfiguration of Applications for Wireless Sensor Networks

The reconfiguration of Wireless Sensor Networks is a well-known problem that has been tackled in the last few years mostly with approaches operating at the network level. In this paper, we introduce an approach for the automated reconfiguration of WSNs, driven by energy problems, at the level of software application. In particular, we define reconfiguration actions with Proteus, that is a framework to specify and implement reconfiguration plans on top of Agilla, that is a mobile agent middleware for Wireless Sensor Networks. A Reconfiguration Engine acts on agents within a WSN to activate reconfiguration plans when required, e.g. when the batteries of several sensors located in a critical geographical area are exhausted. We have started to experiment the approach on a real application.
