Multilateration-based Event Identification in a Wireless Sensor Network

Abstract

Accurately identifying the event detected by the nodes is one of the important characteristics of event-driven applications in Wireless Sensor Networks (WSNs). In a resource-constrained WSN, event identification plays a significant role in identifying similar events reported by the sensor nodes placed in close proximity to each other. This improves the event reliability and also helps in suppressing the dissemination of similar event's information to the sink node. In this paper, we propose to use multilateration-based technique for event identification in a WSN. We performed simulations and provide results for estimation error in identifying the events location.
