Wireless Sensor Networks (WSNs) are a collection of various densely deployed sensor nodes which is implemented in a variety of applications such as home, medical, military, security surveillance and combat field reconnaissance etc. An Event-driven Wireless Sensor Networks (EWSNs) is a type of wireless sensor network in which the desired information is disseminated to the sink more reliably. Another important function of EWSN is the accurate event detection so that the probability of false alarm becomes low. Likewise WSN, sensor nodes in EWSNs are also energy constrained thereby designing energy-efficient algorithm becomes an important factor for extending the life span of the event-driven wireless sensor network.
