Ensuring connectivity in Wireless Sensor Networks (WSN) is a challenging issue, especially in hazardousareas (like battlefield). Many applications of WSN require an important level of connectivity in the networkto detect a given event (like detection Intrusion) and forward it to the ”sink” node in order to alert users.For these risky areas the deterministic deployment is not usually guaranteed and the network is composed
by a set of disconnected Islands. We present in our work two strategies to relocate sensors in order toimprove the connectivity using mobile Robots. These two solutions are called Multi-Robot Island-basedRelocation (MRIBR) and Multi-Robot Grid-Based Island-based Relocation (MRGIR). Through severalsimulations, we show that MRGIR outperforms MRIBR. Our study can be used especially to make a tradeoffbetween the number of deployed sensors and the numbers of the used mobile robots, according to thequality needed for the application.
