The Research On Safty And Efficent Wireless Sensor Networks Routing Protocols

Wireless Sensor Networks can monitor in real-time, sensing, collect and process the information of all kinds of the monitored, it has a very broad application prospects in the military, environmental monitoring and industrial production, also is one of the research issue concerned in the current international. However, there are many questions that need to be settled urgently in the applications of wireless sensor network, especially, how to send the data to the destination safely and effectively making use of very limited energy resources and limited storage space, will become one of the research hotspots and difficulty in wireless sensor network.This paper deeply study the security and node energy efficiency of wireless sensor network routing protocol, the main contributions include:(1) It briefly introduces the research background and significance of of wireless sensor network security, according to its characteristic, classifiedly analyzes its potential safety hazardr, summarizes the research situation, security needs and common attack means of wireless sensor network security, introduces the definition and characteristics application field of provable security, and collected the existing provable security, technology, for WSN, laying a s foundation for the next research work.(2) Applying the main ideas of provable security BCK model, the formalized WSN the working process of routing protocols, mainly includes:the unauthenticated-links adversarial model (UM), authenticated-links model (AM), MT–authentication, then using this model, analyzes the two on-demand routing SRP and Ariadne based on encryption and authentication, and discoveres a new attack. According to the disadvantage of the above two agreements in the safety and effectiveness, the paper proposes a new protocol, EndairA, it strengthens the signature certification and intermediate nodes status transformation and in the process of transmission, routing information is passed on with ciphertext ways to add security to new protocol, applye provable security BCK model to prove the security of new protocol, to meet the two characteristics of definition three, the results shows that this protocol is safe.in this in two model UM and AM(3) It adds EndairA algorithm modules to NS-2 network simulator, and does Simulation experiment on algorithm EndairA from the two aspects: success rate of sending packet and point-to-point time-delay of different nodes, and compares, analyzes, and evaluates the experimental results with SRP and Ariadne algorithm,.The results show that the EndairA algorithm can better save and balance energy consumption of network node, with safety in statistics, and meet the energy efficiency and network scalability requirements.
