【摘要】：物理世界的联网需求和信息世界的扩展需求催生出了一种新类型的网络—物联网。物联网是一个以互联网、传统电信网等为信息载体,通过RFID、无线传感器等各种信息传感设备,让普通物理对象能够被独立寻址,从而实现互联互通功能的网络。随着物联网产业发展迅速,无线传感器网络作为物联网感知层的重要支撑技术成为物联网技术研究的重点领域。无线传感器网络(Wireless Sensor Network, WSN)将大量传感器节点布置到需要监控的区域,通过其自身的自组网能力收集物理世界的数据和信息,而路由协议是数据传输的基础,因此,路由协议是确保WSN高效通信的关键协议之一。由于无线传感器网络中的节点资源有限,并且一般不能补充能量,设计性能高效的无线传感器网络路由协议具有十分重要的意义,所以本论文围绕WSN路由协议展开研究工作。本文通过对国内外研究学者和机构提出的各种无线传感器网络路由协议学习与研究基础上,重视理论和实践相结合,选择已在实际应用部署的无线传感网络系统广泛使用,基于TinyOS系统平台下的CTP路由协议进行研究。本文在分析CTP协议原理的基础上,指出了CTP协议存在负载不均衡的问题,影响网络的能量消耗和生存时间,并针对以上问题设计了负载均衡的无线传感网络V-CTP路由协议。V-CTP协议选择链路指标时,考虑节点所携带子节点的个数和次优路径进行数据转发,设计了虚拟链路指标v-eetx,并用这一指标进行路由选择。本文在保留CTP协议好的机制解决其不足的基础上,设计并在TinyOS平台下实现了V-CTP协议。最后,本文通过在实际的节点平台上进行大量实验,对V-CTP和CTP协议进行性能比较,实验结果表明,V-CTP协议在保证数据传输可靠性的前提下,弥补了CTP协议的不足,实现了负载均衡,降低了网络能量的消耗,延长了网络生存时间。
[Abstract]:The need for networking in the physical world and the expansion of the information world have given birth to a new type of network-the Internet of things.The Internet of things (IoT) is a network with Internet, traditional telecommunication network as information carrier, through RFID, wireless sensor and other information sensing equipment, ordinary physical objects can be independently addressed, so as to achieve the function of interconnection.With the rapid development of the Internet of things (IoT) industry, wireless sensor networks (WSN), as an important supporting technology of the IOT perception layer, has become the key area of the research of IOT technology.Wireless Sensor Network (WSNs) arranges a large number of sensor nodes to the area to be monitored, collects data and information from the physical world through its own self-organizing network capability, and the routing protocol is the basis of data transmission, so,Routing protocol is one of the key protocols to ensure the efficient communication of WSN.Due to the limited resource of nodes in wireless sensor networks and the lack of energy, it is very important to design efficient routing protocols for wireless sensor networks. Therefore, this paper focuses on the research of WSN routing protocols.On the basis of studying and researching various routing protocols of wireless sensor networks put forward by domestic and foreign researchers and institutions, this paper attaches importance to the combination of theory and practice, and selects the wireless sensor network systems which have been deployed in practice and are widely used.Research on CTP routing protocol based on TinyOS system platform.Based on the analysis of the principle of CTP protocol, this paper points out that the CTP protocol has the problem of load imbalance, which affects the energy consumption and lifetime of the network.Aiming at the above problems, a load-balanced V-CTP routing protocol. V-CTP protocol is designed to select the link index, considering the number of sub-nodes carried by the node and the sub-optimal path for data forwarding.A virtual link index v-eetx is designed and used for routing.On the basis of preserving the good mechanism of CTP protocol to solve its shortcomings, this paper designs and implements V-CTP protocol on TinyOS platform.Finally, through a large number of experiments on the actual node platform, this paper compares the performance of V-CTP and CTP protocol. The experimental results show that the V-CTP protocol makes up for the deficiency of CTP protocol on the premise of ensuring the reliability of data transmission.The load balance is realized, the network energy consumption is reduced, and the network lifetime is prolonged.
