In wireless sensor works, the safety of the sensor nodes will directly affect the safety and availability of the entire work. So, this article uses the NS2 simulation platform against malicious nodes on the classical clustering routing protocol algorithm simulation analysis, the reduction on the basis of the algorithm, master the design theory and programming experience, efficient and secure routing protocol was applied to practice, to solve practical problems, so as to improve the performance of the application system, saving energy consumption, etc., for the industrial production and scientific and technological innovation is of great significance. Paper requirements of wireless sensor work node characteristics, type of attack and defense measures in detail, studies the key right by the agreement, select LEACH agreement to indepth study and simulation, especially for malicious node to the existing algorithm is analyzed in terms of security. Based on LEACH routing protocol, by increasing the detecting technology of malicious nodes, introduce more safetySELEACH routing strategy, strategy on the design is given after detailed analysis, reflects the improved algorithm in safety performance optimization, energy utilization and delay the outstanding performance of the work life cycle.
