Energy Efficient Wireless Sensor Networks

With the continuous expansion of computer network scale and the diversity of network equipment, the traditional single computer network maintenance and management method is no longer applicable. Therefore, in order to achieve efficient and accurate management of computer networks and ensure the stable operation of computer networks in various applications, computer network management software with superior performance and corresponding topology discovery technology become the key. In this paper, SNMP (Simple Network Management Protocol) network topology discovery algorithm is deeply analyzed in the laboratory computer network environment, and its shortcomings are pointed out. In view of the shortcomings of traditional SNMP algorithm, this algorithm is optimized and improved, and helps ICMP (Internet Control Message Protocol) detect the internal subnet, so as to discover the main network topology accurately and efficiently. In order to solve the heterogeneity of information storage modes in MIB (Management Information Base) libraries of different devices in laboratory network environment, this paper innovatively adds an optimized SNMP algorithm aiming at the heterogeneity of network devices, thus realizing the universality of network topology. Finally, the experiments show that the time dissipation of the proposed algorithm is less than 10 data points compared with the traditional algorithm under the same experimental conditions. The laboratory network environment based on the proposed system can achieve a fast and smooth laboratory network, which has obvious advantages compared with the traditional network management system.
