Research On Address Assignment Mechanism And Algorithm Of Asymmetric ZigBee Network

Address allocation mechanism of ZigBee network is an important factor in the success rate of ZigBee networking.But the current distributed address allocation mechanism is usually suitable for symmetrical networks.Faced with a large number of asymmetric networks in the actual scene,existing allocation mechanisms are prone to address exhaustion and limited network depth.In view of the above problems,this paper designs an asymmetric ZigBee network address allocation mechanism and an address dynamic adjustment algorithm from the perspectives of address pool application and network deepening.The specific work is as follows:First,the address allocation mechanisms and routing algorithms ZigBee protocol has been the focus of research.It also derives the distributed address allocation formula used by the ZigBee protocol.At the same time,the paper analyzes the main problems existing in it,and demonstrates the importance of designing an address allocation mechanism for asymmetric ZigBee networks.This paper proposes an asymmetric address pool assignment mechanism)(AAPAM)for asymmetric ZigBee networks and a dynamic adjustment algorithm under this mechanism.The node can apply for the corresponding size of the address pool according to its own requirements,and no longer use the maximum depth parameter,so that the network can be effectively expanded,Finally the paper verifies the mechanism by Matlab simulation experiments.In this paper,the AAPAM hardware networking communication experiment is designed.The CC2530 chip is used to construct the ZigBee module and combined with the BasicRP protocol networking.Then the principle and flow of the experiment are introduced in detail from two parts of hardware and software.Finally,the result of the experiment is displayed by computer.The asymmetric ZigBee network address allocation mechanism designed in this paper can realize large-scale networking in complex networks,which will provides strong support for the development and application of ZigBee wireless communication technology.
