1 Introduction
Recent advances in microelectro-mechanical systems and wireless communications
have enabled the development of distributed, wireless networks of small,
inexpensive, low power sensors. These sensors, which possess sensing, data
processing and short range communication capabilities, can be deployed in
diverse environments to collect useful information. Large numbers of such inexpensive
sensors form ad hoc wireless networks which can be used in a variety
of commercial and military applications.
As sensors become inexpensive and widely available, sensor networks can
be deployed in larger scales. One of the issues arising consequently is scalability.
A flat structure of a large number of sensors often provides low scalability
and makes network-wide coordination di?±cult. To solve this problem, hierarchical
architectures (clusters) have been proposed to solve the scalability
problem.
