Design and Analysis of a Data Fusion Scheme in Mobile Wireless Sensor Networks Based on Multi-Protocol Mobile Agents

Abstract

Sensors are increasingly used in mobile environments with wireless network connections. Multiple sensor types measure distinct aspects of the same event. Their measurements are then combined to produce integrated, reliable results. As the number of sensors in networks increases, low energy requirements and changing network connections complicate event detection and measurement. We present a data fusion scheme for use in mobile wireless sensor networks with high energy efficiency and low network delays, that still produces reliable results. In the first phase, we used a network simulation where mobile agents dynamically select the next hop migration node based on the stability parameter of the link, and perform the data fusion at the migration node. Agents use the fusion results to decide if it should return the fusion results to the processing center or continue to collect more data. In the second phase. The feasibility of data fusion at the node level is confirmed by an experimental design where fused data from color sensors show near-identical results to actual physical temperatures. These results are potentially important for new large-scale sensor network applications.

High-density data transmission and scheduling method in wireless sensor networks based on Wi-Fi

“…The data frame format and execution time of the task in the same virtual subnet are the same, so the order in which the tasks are executed does not change the generation time and size of the data packet. 25,26 This is used as the theoretical basis to realize the transmission scheduling of high-density data in wireless sensor networks.…”

“…Data-fusion algorithms inspired by fuzzy entropy have been proposed to improve the reliability of WSNs [58]. Multiprotocol mobile agents have also been used to design and analyze data-fusion schemes in mobile WSNs [59].…”

A New Path-Constrained Rendezvous Planning Approach for Large-Scale Event-Driven Wireless Sensor Networks

“…Recently, employing mobile-sink(s) in the network becomes one of the efficient solutions to balance energy-consumption among the sensor-nodes [ 8 , 9 , 10 , 11 , 12 , 13 ]. The main idea behind this solution is that the mobile-sink(s) can move across the network and harvest the data from the sensor-nodes and reduce or eliminate the number of hops in the fashion of multi-hop communication.…”
