Design And Implementation Of Wireless Network Based On AODV

The development of technology for Internet of Things(IOT) changes people’s life every minute nowadays. The foundation of IOT is internetwork and WSN of which the core problem is wireless network. The fundamental feature of wireless network is that every node is a host and a router as well, and data can be retransmitted through adjacent nodes to destinations. In order to achieve the wireless network, many scientific researchers put forward many algorithms and apply to all walks of life in recent years. In this paper,the characteristics of existing algorithms of wireless network are analyzed firstly; in the meanwhile, the AODV algorithm is deeply studied. According to the need of the project,router judgment index algorithm in AODA algorithm has been improved to some extent.Determining the router through calculating the router communition success rate makes the communition success rate of wireless network improved greatly. Secondly, according to the actual needs of the project, the design of the application layer retransmission and validation algorithm ensures the prevention of packet loss and packet reception repeated as well in the process of communication to achieve effective data transmission. Thirdly,the use of STM32 SCM and nRF24L01 chip for the design of wireless unite, the use of STM32 SCM and W5500 chip for the design of wireless/Ethernet gateway, all these designs get the effect of data transmission from wireless node to internet. At last, test software is designed and performance test of software and hardware is implemented in the actual environment. The test result shows that wireless hardware system is stable,real-time of improved agreement is enhanced compared with AODV algorithm. The system of application layer has a good effect. The anticipated effect is fulfilled in this paper.
