Optimal Base Station Placement in Wireless Sensor Networks

Free registration required

Executive Summary

An important performance metric for wireless sensor networks is the so-called network lifetime, which is highly dependent upon the physical topology of the network. This is because energy expenditure at a node to transmit data to another node not only depends on the data bit rate, but also on the physical distance between these two nodes. Consequently, it is important to understand the impact of location related issues on network lifetime performance and to optimize topology during network deployment stage. This paper considers the important base station placement problem for a given sensor network such that network lifetime can be maximized.
