Clustered Zigbee Networks With Data Fusion: Characterization and Performance Analysis

Free registration required

Executive Summary

In this paper, the authors analyze the performance of clustered Zigbee Wireless Sensor Networks (WSNs) with data fusion. Performance indicators at both physical (probability of decision error) and network (network transmission rate, throughput, aggregate throughput, delay, and network lifetime) layers are considered. Data fusion is carried out at the Access Point (AP) and, in clustered configurations, also at the clusterheads, which act as intermediate Fusion Centers (FCs). The goal of this paper is to shed light on the joint impact of topology and data fusion on the network performance.
