The Research On Mulitcasting Algorithms Based On ZigBee Wireless Sensor Network Layer

Internet of Things (IOT) is one of today's hottest technology researches, the State Council has issued relevant documents in order to promote the orderly and healthy development of the Internet of Things as a strategic emerging industries. Internet of Things refers to the Internet which things and things interconnected, where the main medium of interconnected using wireless technology. Wireless sensor network technology plays an important role for the development of the Internet of Things. ZigBee wireless sensor network technology is used widely in networking technology, mainly for building automation transmission of information, industrial production control, clinical care and other fields. ZigBee modules generally use a battery-powered, for the rational use of energy is essential. Multicast communications as an efficient and practical transmission scheme is widely applied in the ZigBee network. However, the existing ZigBee multicast routing algorithm is not enough to consider the use of energy. Many algorithms work inefficiency or only focus on efficiency and ignore the node energy. This leads to a ZigBee network cannot run for a long time. Therefore, exploit an energy efficient ZigBee multicast routing algorithm is very important.The purpose of this paper is to use ZigBee neighbor query function to design efficient multicast routing algorithm for ZigBee, ZigBee multicast routing algorithm based on neighbor table query and Distributed energy balance ZigBee multicast routing algorithm based on the neighbor table. In the ZigBee multicast routing algorithm based on neighbor table query, to ease the problem ZigBee network information pass by multicast manner, some nodes repeatedly consume large amounts of energy. Algorithm combined with neighbor query and ZigBee distributed address allocation features. Before source forwarding the multicast information, optimize ZigBee network multicast forwarding node selection. Node forwards the information to multiple destination nodes, reduces the routing overhead, saves energy networks, to improve the efficiency of routing nodes forwarding; In the Distributed energy balance ZigBee multicast routing algorithm based on the neighbor table. In order to improve the overall performance of ZigBee network considering node energy and routing costs. Select the remaining routing more energy and less energy loss after forwarding network nodes, the nodes to prevent the high frequency of use depletion leads to the death of nodes and prolong the network lifetime. In this paper, using MatLab simulate algorithm. ZigBee multicast routing algorithm based on neighbor table query and Distributed energy balance ZigBee multicast routing algorithm based on the neighbor table. Experimental results show that ZigBee multicast routing algorithm based on neighbor table query can effectively reduce the number of network energy savings, improve the efficiency of routing nodes. Distributed energy balance ZigBee multicast routing algorithm can effectively reduce the energy consumption of the entire network node to postpone the time of death, to extend the network lifetime.ZigBee technology is widely used in the Internet of Things, information often sent in multicast mode specified node to the network. Multicast routing is a reasonable choice can improve the overall performance of ZigBee network. Two algorithms proposed improves the ZigBee network multicast message transmission performance and prolong the life of the whole network and generally apply to existing ZigBee networks. If apply into production will have good economic and social benefits, the two algorithms are expected to use in the field of ZigBee network multicast routing algorithms.
