The implementation of a division cluster scheduling algorithm

Abstract

As a typical resource constrained system,Wireless Sensor Network (WSN) can be significantly improved the performance of guarantee quality of service (QoS) by effective resource allocation,including channel and time slot. But the structure is not fixed in smart medical system,which can lead to the uncertainty service quality. A non-balanced cluster tree structure is present for overcoming the collision and uncertain delay,taking into account the allocation of traffic. The resource parameter is implemented in TinyOS system,which be verified by CC2530 platform. And Graphical User Interface is designed for modifying data flow parameters and inspecting scheduling results. The experimental results show that this cluster tree scheduling algorithm can ensure the non-balanced structure of network quality,and provide the effective service guarantee for large-scale cluster tree network.
