Time Clock Offset on WSN

Using Time Clock Offset of The Wireless Sensor Node Authentication Method

Wireless sensor networks the information provided by the sensor nodes, thus ensuring that all nodes on the network time synchronization is a necessary condition to maintain the data can be correctly interpreted. Compared to other research results, flooding time synchronization protocol (FTSP) to provide the most accurate timing functions, this Agreement, however, were not considered in the design of the prevention of a variety of attacks, especially the lack of root identification mechanism. On the other hand, the identification mechanism of the clock offset and the development of sensor nodes in the applicant study has preliminary results. Clock offset to the current still can not disguise, the required computational cost and memory needs are less than a variety of sufficient strength encryption method, and therefore very suitable for applications in wireless sensor. The purpose of this project two years before the continuation of the applicant’s research, the time synchronization protocol for wireless sensor networks on the security improvements, and the use of clock skew to develop an innovative authentication mechanisms. The first year of the plan targets to be amended FTSP program code and node identification method has been developed embedded into FTSP, so that the sensor nodes may independently identify the surrounding nodes. The second year aims to expand the node identification method to the multi-hop environment, at the same time feedback to the FTSP to address the weaknesses of its root node selection algorithm. The third goal is to try and node identification method of packaging as an independent module to attempt to transplant to the MANET, VANET environment.
