A secure network coverage protocol of WSNs

Wireless sensor networks(WSNs) are widely used in many applications, however in some hostile scenarios WSNs are susceptible to many malicious attacks. Due to various source limitations and salient features of WSNs, the security design for such networks is significantly challenging. we propose a secure protocol to provide current network coverage information. In contrast to previous security mechanisms, our approaches feature nearly perfect resilience to node compromise, low communication and computation overhead, low memory requirements, and high network scalability.
