Data Transmission Reduction in Wireless Sensor Network for Spatial Event Detection

Abstract

Wireless sensor networks have found many applications in detecting events such as security threats, natural hazards, or technical malfunctions. An essential requirement for event detection systems is the long lifetime of battery-powered sensor nodes. This paper introduces a new method for prolonging the wireless sensor network’s lifetime by reducing data transmissions between neighboring sensor nodes that cooperate in event detection. The proposed method allows sensor nodes to decide whether they need to exchange sensor readings for correctly detecting events. The sensor node takes into account the detection algorithm and verifies whether its current sensor readings can impact the event detection performed by another node. The data are transmitted only when they are found to be necessary for event detection. The proposed method was implemented in a wireless sensor network to detect the instability of cargo boxes during transportation. Experimental evaluation confirmed that the proposed method significantly extends the network lifetime and ensures the accurate detection of events. It was also shown that the introduced method is more effective in reducing data transmissions than the state-of-the-art event-triggered transmission and dual prediction algorithms.

Design of Remote Real-Time Monitoring and Control Management System for Smart Home Equipment Based on Wireless Multihop Sensor Network

“…In addition, the change of social environment also has a new impact on people's way of life, so people's demand for a perfect home security system is also more urgent. For the traditional form of civil air defense, security has been unable to meet the new needs of the eyes, so the concept of smart home with the fundamental purpose of providing a safe, comfortable, and convenient living environment has gradually emerged, and the safety monitoring system in smart home system has also become a key research part [5][6][7].…”
