SLAM: Sleep-Wake Aware Local Monitoring in Sensor Networks
Sleep-wake protocols are critical in sensor networks to ensure long-lived operation. However, an open problem is how to develop efficient mechanisms that can be incorporated with sleep-wake protocols to ensure both longlived operation and a high degree of security. Our contribution in this paper is to address this problem by using local monitoring, a powerful technique for detecting and mitigating control and data attacks in sensor networks. In local monitoring, each node oversees part of the traffic going in and out of its neighbors to determine if the behavior is suspicious, such as, unusually long delay in forwarding a packet. Here, we present a protocol called SLAM to make local monitoring parsimonious in its energy consumption and to integrate it with any extant sleep-wake protocol in the network. The challenge is to enable sleep-wake in a secure manner even in the face of nodes that may be adversarial and not wake up nodes responsible for monitoring its traffic. We prove analyti...
