Research On Routing Of The Internet Of Heat Meter Base On ZigBee

IEEE802.15.4/ZigBee used as a specialized field of wireless sensor networks for lowcomplexity,low data rate, low cost communication technology standards has been moremore and more used in practical application.Different with other network communicationtechnology, ZigBee is a kind of energy limited network,and its energy extremely limitedin operation process.So more and more people pay attention to research the problem ofhow to maximum extend the lifetime of ZigBee network in the limited energy.First of all,Combined with the ZigBee network topology structure and the datatransmission model in the internet of heat meter things applications, this paper proposed aL-ZBR (Leach ZigBee Routing)routing algorithm based on key nodes. It sets the energythreshold of the key nodes according to the size of network and the structure networktopology, and finds a agent father node of child routing nodes of the nodes whose energyconsumption reaches the threshold of key nodes. The auxiliary routing path is establishedthrough the agent father node and it can share the data forwarding task of the original keynode. Prolong the survival period of purpose.Secondly, Through the analysis and research IEEE802.15.4networking connectionmechanism, In order to slove the problem of the the new node selection distance recentcandidate nodes as the parent node is apt to cause the overall network depth increase,andsome nodes load imbalance in the process of network, This paper proposed a LRZ (LinearRegression ZigBee) network algorithm, its comprehensive consideration candidate fathernode depth and load state of Thereby, it can reduce the network overall depth andbalanced node load state, and optimize the network topology.Finally, on the NS2simulation platform construction ZigBee respectively, the L-ZBR routing algorithm and LRZ network algorithm simulation, and from the networktopology, the lifetime of network, the number of death node, group submitted rate,network,the residual energy of network before and after five aspects to improve thealgorithm performance comparison and analysis.
