Study of building low-cost pervasive network and optimizing its services
Yiqiang Chen · Computer Engineering and Applications Journal · 2010
Bluetooth technology has advantages of low-cost,low-coverage,high-speed and convenience to build piconet,while Zig-Bee technology has advantages of low-cost,low-complexity and high-capability of building long-distance networks.This paper tries to fully utilize these complimentary features,and design a low-cost pervasive network on these two technologies.Moreover,this pa-per proposes a user-property-based access algorithm and a priority-based bandwidth allocation algorithm.The hardware of this system includes ARM,bluetooth,ZigBee and sensor modules,and the operation is open-source Linux.The access and bandwidth allocation algorithms exhibit better performance than average-allocation algorithm,in term of efficiency and service time.
