Energy consumption is ranked among the major problems of research in wireless sensor networks(WSNs). The main reason for nodes failure is the discharge of batteries in sensor networks. Therefore, energy consumption plays an important role in wireless sensor networks. Data aggregation can greatly help to reduce this consumption by eliminating redundant data, and using clustering methods for data aggregation helps to further reduce energy consumption. Sensor nodes are prone to node compromise attacks which cause an adversary to change the aggregation result and inject false data into the WSN, hence security issues such as data confidentiality and integrity are extremely important. Because both data aggregation and security are critical for wireless sensor networks, achieving secure data aggregation that protects integrity is a critical issue. In this paper, we present a secure data aggregation method called Energy-Efficient and Privacy-Preserving Data Aggregation using our clustering algorithm which is an improvement on LEACH protocol and Homomorphic Encryption technique.

This study analyzes the institutions that have been used for science and technology policy in the Islamic Republic of Iran since the Pahlavi era (first and second Pahlavi) until now. Institutions that were created during this period and their duties and powers are briefly mentioned and approaches such as modernization and modernization in the Pahlavi era, redefining values and value creation based on Islamic indicators in the period. After the Revolution of 1978, which were the source of the institutions of their time, using the historical method (prevailing environmental conditions) and the focus group, this trend was analyzed and in the final part in the form of conclusions, policy recommendations that From this analysis, it has been obtained such as merging some institutions, determining the unity mechanism of the same plurality of policy makers and implementers, vertical and horizontal strategic coordination between programs and macro documents in this field, and finally practical suggestions and suggestions for future research. .
