[Abstract]:Wireless ad hoc networks (WSNs) have attracted much attention because of their ability to quickly set up networks without preset communication devices. At present, the research of wireless ad hoc network routing protocols is mainly focused on the theoretical design and simulation experiments, and lack of verification and testing in real environment. The wireless ad hoc network routing protocol testing platform can implement the wireless ad hoc network routing protocol in real environment, and complete the related functional testing and performance testing. The main work of this paper is as follows: 1. This paper introduces the wireless ad hoc network and its typical routing protocols, analyzes the characteristics of the wireless ad hoc network routing protocols, and studies the routing tables of the typical on-demand driven routing protocols (AODV) and the typical table-driven routing protocols (DSDV). Routing control message structure and routing algorithm. This paper also introduces the free open source library Win Pcap,Linux operating system and Linux network framework under the Windows platform. 2. By analyzing the wireless ad hoc network protocol stack and combining the characteristics of Linux operating system and Windows operating system, this paper designs the implementation scheme of wireless ad hoc network routing protocol test platform under multiple operating systems. This scheme does not need to modify the operating system kernel, and implements the wireless ad hoc network protocol stack by adding extension modules in user space. Design for the platform routing protocol changes and platform function extension left a good interface. 3. In this paper, the PC computer with IEEE 802.11b network card is selected as the test platform, and the Linux operating system and Windows operating system are used as the multi-system environment. The implementation scheme under Linux platform mainly includes routing protocol algorithm module, temporary routing table module. The kernel routing table synchronization module, the operating system kernel space and the user space interface, the non-routing packet cache module. Under the Windows platform realization scheme mainly includes the data transceiver interface, the data packet analysis module. Data cache module and routing protocol algorithm module. The two test platforms designed and implemented in this paper, Linux operating system and Windows operating system, can form heterogeneous networks, which have wide application prospect and great commercial value. 4. This paper uses the wireless ad hoc network routing protocol test platform to build heterogeneous multi-hop network for testing. Firstly, the function of routing protocol is tested by using the test platform. The test results show that the platform can realize the corresponding functions of wireless ad hoc network and meet the design requirements. Then, the routing discovery time of AODV routing protocol is tested by the test platform, and the test results are analyzed. Finally, the end-to-end throughput of the platform using AODV routing protocol and DSDV routing protocol is tested and the test results are analyzed.
