Based on the given sensitivity, sensors can locate the moving object in the monitored area and form a tracking cluster around it. This tracking cluster can follow the target logically, process data on the target and report to the sink node, and thus achieve the tracking function. We introduce a multi-path reinforcement scheme, q-composition scheme and one-way cryptographic hash function based random key predistribution algorithm （RKP）, which can guarantee a high accuracy and security and a low energy consumption on the same time in large-scale sensor networks.展开更多

文摘In the historical period of the all-round deepening reform,China has entered a new era of“deepening the practice of governing the country by law”.With the fifth amendment of the Constitution,the legislative power of local government has been further confirmed.The expansion of local legislative power has put forward new requirements for the legislative quality,and the pre-legislative evaluation system has thus come into being.The deficiency of the design of the pre-legislative evaluation system in Article 39 of The Legislative Law makes certain problems in the detailed rules of implementation,the subject of evaluation,the object of evaluation and the personnel of the pre-legislative evaluation system in China.Therefore,it is the only way to perfect the pre-legislative evaluation system in China to formulate a national pre-legislative evaluation implementation rules,define the subject of third-party evaluation,determine the scope of evaluation objects and select the suitable evaluation personnel.
