The Research Of Wireless Sensor Network Privacy Protection Based On Network Coding

Wireless sensor network (WSN) related technology increasingly developed and mature, In wirele-ss sensor network deployment of applications has emerged in the privacy problem is becoming more and more serious, This is also the bottleneck in the application of wireless sensor technology.But p-rivacy issues in wireless sensor networks because of its specific application related and resource feat-ures such as limited shows the characteristics of unique and distinctive, The protection mechanism a nd algorithm for privacy problems existing lost utility, So the urgent needs to design a practical privac-y protection mechanism.In the traditional routing mode, Receiving node only information and forwarding, We propose a network coding theory completely broke the traditional way.Using the nodes of the network coding t-echniquecan be the combination of code to a different link information, Then the coding information forwarded.Studies have shown that, The features of network coding include to improve the through-put of network, The network load balancing, Improving the information transmission security, Tor-educe the energy consumption of nodes, To improve fault tolerance of network and reduce the trans-mission delay.By the above characteristics show, In Wireless Sensor Networks, Network coding tec-hnology has its full application in space.This paper firstly for privacy protection problems in wireless sensor, Analysis and comparison of several existing protection mechanisms. And then the encoding principle of network coding is brie-fly discussed, And introduces the common network coding scheme. This paper focuses on the resear-ch of network coding in wireless sensor network data and location privacy protection strategy based on, For example, in the discussion on the strategy of location privacy protection were privacy for loc-ation of source node and sink node are analyzed; In the analysis of network data protection strateg y is discussed in detail the integrity protection of data privacy and access control strategy of WSN. Research shows that:The new scheme with the traditional method of comparison, Energy consum-ption has been effectively reduced, Real time network privacy protection task also satisfied.
