A unified event reporting solution for wireless sensor networks

Abstract

Wireless sensor networks are deployed to observe a variety of events from the sensor field. Each event can have different constraints in terms of reporting rate, fairness, priorities and real-time information delivery. A number of event reporting, transport, congestion and rate control schemes have been proposed in the existing literature. However, these solutions have been proposed for different applications, spanning on different layers of protocol stack with contradicting basic assumptions. Therefore, due to the architectural and operational differences of these solutions, existing protocols are not appropriate to operate in a unified manner at the transport layer of sensor networks. This work presents a unified scalable, energy-aware and flexible event reporting solution for wireless sensor networks. The proposed event reporting solution provides different modes for event reporting like simple, fair, prioritized and real-time. Simulation study proves that the proposed event reporting solution provides maximum throughput, high packet delivery ratio, low energy consumption and achieves different event reporting mode requirements.
