![]() A scatternet should be formed in such a way that batteries of mobile devices are efficiently used in order to lengthen scatternet lifetime.We discuss the problem of energy-efficient topology construction and maintenance for Bluetooth scatternets. As the Bluetooth topology grows from isolated piconets to a scatternet, energy-efficiency becomes a critical issue since additional power is consumed for multi-hop routing. Building larger ad hoc networks is possible by interconnecting multiple piconets to form a scatternet. Using Bluetooth technology, a small number of closely located devices can be interconnected within a piconet. Bluetooth is a short-range ad hoc networking technology, which enables formation of inexpensive personal area networks with low power consumption.
