Wireless Sensor Network (WSN) consists of many nodes. WSNs are used for many applications such as military and battlefield monitoring. So, deploying wireless sensor networks in public environments may become necessary to provide security against possible attacks such as node-compromise andeavesdropping. Beside these problems, the sensor nodes are battery powered thus energy is the most precious resource. So that, to provide security and energy consumption should be in balance state. Therefore, in this paper, we purpose a new method to provide confidentiality of data between nodes tosend base station. In the proposed method, we use some special nodes as cluster head (CH) which have long radio range. A node encrypts the data and sends it to the nearest neighbor until the data receives to CH, and then it encrypts and sends to the base station. Finally, proposed method will be evaluated by different encryption algorithm on different platforms.
