6LoWPAN网络能量均衡与NAT64边缘路由研究
[Abstract]:Extending wireless sensor network (Wireless Sensor Networks,WSN) to IP network to realize the interconnection between wireless sensor network and Internet is one of the problems that need to be solved in the process of WSN industrialization. It is also the inevitable trend of the development of wireless sensor network and Internet. In addition, the power consumption of wireless sensor networks has been the bottleneck to limit the whole life cycle of low-power lossy networks. Effectively reducing the power consumption of the network, especially the power consumption of the nodes around the root node, is related to the effective survival time of the whole network. However, at present, the edge router based on 6LoWPAN (IPv6 over Low Power Wireless Personal Area Networks) is only suitable for interconnection with IPv6 devices, the transmission of network packets is complicated and cumbersome, the mapping table of edge router is complex and expensive, and so on. In the low power consumption lossy network based on RPL, the edge router has some disadvantages. After the node runs for a long time, the network will appear energy imbalance, easy to fluctuate, poor routing and other problems. This paper focuses on the following aspects: (1) introduce the concept of IEEE 802.15.4 address to optimize the packet format and message interaction mode in 6LoWPAN network, aiming at the problem of interconnection between 6LoWPAN network and IPv4. This paper presents a protocol translation mechanism between 6LoWPAN and IPv4 and an address mapping method for edge routers. Aiming at the problem of energy balance in 6LoWPAN network, a network model with RPL (Routing Protocol for LLN) characteristics is proposed. The energy balance dynamic routing algorithm based on compound metrics is designed. (2) the edge router based on NAT64 and the energy equalization routing algorithm based on RPL are designed. The transition protocol between IPv6 and IPv4, RPL objective function and metric selection are introduced in detail. The protocol conversion and implementation method suitable for running on 8-bit single-chip computer are put forward. (3) the lightweight system is designed and implemented. Finally, CoAP (Constrained Application Protocol) protocol is used to access node data and verify the system. The communication between 6LoWPAN network and IPv4,IPv6 network is realized. The energy balance routing algorithm is designed and implemented, and the algorithm is simulated. The research of this subject realizes the communication between 6LoWPAN and IPv4 network, improves the throughput of 6LoWPAN network, reduces the overhead of maintaining address mapping table for edge routers, improves the efficiency of edge routers, and effectively reduces the power consumption when 6LoWPAN networks transmit data. Improve the survival time of nodes. The energy balance routing algorithm realizes the load balance of the whole network under the condition of ensuring the real-time and integrity of the data. The simulation results show that the model is suitable for the RPL type network, and the corresponding algorithm can select the optimal link according to the measurement rules. The optimal parent node, while maintaining network stability, effectively prolongs the effective working time of the network. The research of this topic provides the theoretical basis and technical support for the energy balance of 6LoWPAN and Internet interworking 6LoWPAN network. It has important practical significance and practical value to solve the problem of industrialization of 6LoWPAN network and the problem of effective survival time.
