A Centralized Time-slot Leasing-based Qos Routing Protocol over Bluetooth Wpans

چکیده
ABSTRACT In this paper, we investigate a new efficient quality of service (QoS) routing protocol based on the time-slot leasing mechanism over Bluetooth wireless personal area networks (WPANs). In a Bluetooth scatternet, a QoS route path is constructed through a series of QoS slave-masterslave communications. The ”transmission holding” problem is incurred because the master node is the communication bottleneck for each slave-master-slave communication. To alleviate this problem, a time-slot leasing scheme is adaptively incorporated into our scheme to provide a completely new QoS routing protocol. This QoS routing protocol can additionally offer extra slave-to-slave QoS communication capability to effectively reduce the workload of the master node and significantly promote the success rate of finding a QoS route. In our proposed QoS routing protocol, QoS slave-master-slave and slave-to-slave communication mechanisms are simultaneously considered in order to achieve a high success rate of QoS routing from the source to destination nodes. Finally, simulation results demonstrate that this time-slot leasing-based QoS routing protocol can significantly improve the success ratio, delay time, throughput, and bandwidth utilization when compared to other existing QoS routing protocols.

متن کاملAn Overlapping Communication Protocol Using Improved Time-Slot Leasing for Bluetooth WPANs
In this paper, we propose an overlapping communication protocol using improved time-slot leasing in the Bluetooth WPANS. One or many slave–master–slave communications usually exist in a piconet of the Bluetooth network. A fatal communication bottleneck is incurred in the master node if many slave–master–slave communications are required at the same time. To alleviate the problem, an overlapping...

Bluetooth is a promising wireless technology aiming at supporting electronic devices to be instantly interconnected into short-range ad hoc networks. The Bluetooth medium access control protocol is based on the Master/Slave concept wherein any communication between slave devices has to go through the Master. While this model is simple, it incurs longer delay between any two slave devices due to...

Mobile ad hoc networks (MANET) is a self-organized collection of nodes that communicates without any infrastructure. Providing quality of service (QoS) in such networks is a competitive task due to unreliable wireless link, mobility, lack of centralized coordination, and channel contention. The success of many real time applications is purely based on the QoS, which can be achieved by quality a...
