PERFORMANCE ANALYSIS OF LARGE-SCALE WIRELESS SENSOR NETWORK ARCHITECTURE WITH MULTI-CLUSTER CONFIGURATION

摘要

Large-scale sensor networks containing many sensor nodes are often divided into clusters so large that necessary to use multi-hop communication between cluster heads when collecting data. In this paper we derive analytically how parameters such as the communication distance of a cluster head affect the power consumption and throughput of such networks. We also that power consumption can be reduced and throughput roughly doubled by not unnecessarily relaying data in the neighborhood of the sink node.
