Scatternet Formation of Bluetooth Ad Hoc Networks
Found in: Hawaii International Conference on System Sciences
By Bin Zhen, Jonghun Park, Yongsuk Kim
Issue Date:January 2003
pp. 312b
Scatternet formation must be addressed before any ad hoc network protocol can be run over Bluetooth. This is due to the frequency hop nature and piconet unit of Bluetooth. In this paper, a protocol stack of Bluetooth group ad hoc network and a
Joint Optimization of Index Freshness and Coverage in Real-Time Search Engines
