Abstract:	The Bluetooth [1] device randomly searches and connects with other devices using the inquiry/inquiry scan and the page/page scan operations, resulting an uncontrolled scatternet topoloty. The unpredictable scatternet topology usually raises the problem of redundant traffic and causes inefficient communications. A Traffic-Aware Restructuring Protocol (TARP) is presented for partially restructuring a piconet or neighboring piconets by applying role switch mechanism. According to the recent routes and their traffic pattern, the TARP adjusts piconet structure by selecting the proper master from devices of a piconet and switches proper devices of neighboring piconets to reduce the route length and thus improve the power and bandwidth consumptions and transmission delay. Performance results reveal that the proposed restructuring protocols reduce path length of recent routes and traffic load in scatternet and saves power consumption, thus significantly improves the performance for a given connected scatternet.
