Securing physical borders is a critical task and a real concern for all the countries over the world. Conventional techniques which have been largely investigated to secure borders over the past, are progressively abandoned due to the intensive human involvement and high maintenance costs. Recently, new technologies, such as Wireless Sensor Networks (WSN), have been implemented to reduce the costs and improve the efficiency of the border surveillance system. One of the critical issue in WSN it to define an efficient activation strategy of the different sensors to reduce the resource consumption and enhance the lifetime of the network. We propose in this paper to study the effectiveness of adapting the activation period of scalar sensors and cameras on the lifetime of the network. Simulation results show that this period should be reduced in crisis time to enhance the fault tolerance of the network while it should be augmented in peacetime to extend the network lifetime.
