Deployment of Sparse Sensor-Actuator Network in a Virtual Architecture

The use of a virtual architecture in wireless sensor networks provides a powerful and fast partitioning into a set of clusters, each being locatable in space by the sink or base station (BS for short). We first propose a protocol for the detection of empty clusters due to poor distribution of sensors or in low-density network. After this detection, we propose a strategy to allow mobile sensors (actuators) to move to position themselves on empty clusters in order to improve the routing of collected data.
