Guaranteeing QoS in Bluetooth Scatternet Sensor Network
Bluetooth is a low power and cost-effective short range wireless network technology working in 2.4GHz ISM band. Bluetooth can be implemented either in piconet or scatternet. In piconet the devices can communicate with each other forming a network with maximum of 8 nodes (1 master and 7 slaves). Two or more piconets can be connected through a common Bluetooth device (a gateway or bridge) to form a Scatternet. But the difficult thing is to achieve Quality of Service (QoS) in Bluetooth particularly in the Scatternet. Quality of Service (QoS) refers to the efficient management of system resources, which includes the parameters like bandwidth, delay, jitter etc.
