Wireless sensor network composed of infrastructureless, small, low-power, low cost, dynamic nature, application oriented, and multihoping wireless nodes, design for the purpose of collecting information by environment sensing, processing and communication. Designing of these networks become more complicated due to deploy nodes characterstics, maintenance of database, security, authentication an...

Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...
