[Abstract]:With the development of wireless meter reading technology, the application of wireless ad hoc network in meter reading has been promoted. Routing algorithms directly affect the performance of wireless networks and are crucial to wireless networks, such as the reliability of routing algorithms, throughput, packet loss rate, end-to-end delay and other key indicators. At present, there are many classical routing algorithms, such as dynamic source routing algorithm (DSR (Dynamic Source Routing), target node sequence distance vector protocol (DSDV (Destination Sequenced Distance Vctor), on-demand routing algorithm (AODV (Ad hoc On Demand Distance Vector), and so on. It plays an important role in wireless ad hoc networks. This paper presents an improved scheme based on the classical routing algorithm DSR. In this paper, the structure and working principle of wireless meter reading system and the development of wireless communication technology are introduced briefly, which lays a foundation for further understanding the routing algorithm in wireless meter reading system. This paper mainly studies the routing algorithm in the wireless meter reading system, and then improves it based on the classical DSR routing algorithm. The DSR routing algorithm is introduced briefly and the working principle of DSR is understood. The improved DSR routing algorithm is further completed from two aspects: route establishment and route maintenance. This paper introduces in detail the DSRM algorithm based on the improved DSR routing algorithm, from the process of route establishment and maintenance, as well as the message format used in the routing algorithm, such as RREQ,RREP, to complete the in-depth understanding of the routing algorithm. The routing time is shortened and the packet loss rate is reduced, and the reliable transmission performance of data is improved. This paper presents the simulation of DSRM routing algorithm based on NS2 software, compares and analyzes the performance of DSR routing algorithm and DSRM routing algorithm, and shows the difference between them by using XGRAPH software.
