Event Detection and Information Passing Using LEACH Protocol in Wireless Sensor Networks

Abstract

Wireless Sensor Networks plays an important role in creating and developing smart environments. It includes sensors geographically distributed which are interconnected and hence forming a wireless network. Under any hazardous and danger prone situations, these sensors can detect the event occurred and inform the nearest service zones (base station). In construction sites for fence monitoring, when an event occurs around the fence, the nearby sensor nodes detect the event and pass this information to the neighbouring nodes until it reaches the nearest base station (service zones) using Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. The events are classified using classification algorithm implemented at each sensor node. Since power consumption is an important criterion, the communication among the nodes should be energy efficient and the proposed system achieves around 13% less energy consumption. To simulate this environment, NETSIM simulation tool is used and the occurred events are classified into critical or non-critical events.
