Time synchronization is a vitally important service for all distributed systems. Wireless Sensor Networks (WSNs), which, generally, are designed to operate with stringent set of constraints, require time synchronization services especially for accomplishing the functionality expected from them. In literature there are various time synchronization protocols… (More)
Critical Infrastructure Security had always been an issue. With the technological advancements, there has been a continuous inflow of novel methods for critical infrastructure security. In this paper, design, implementation, and field tests of a novel critical infrastructure security system based on wireless sensor networks is presented.
