Abstract: A wireless sensor network (WSN) consists of sensor nodes with low cost and limited performance. The energy needed for node management is important because it is difficult to manage the deployed nodes. Several traditional security protocols prevent several known attacks in WSNs, such as s false report injection attack. However, the traditional protocols do not consider the false traffic ratio and geographical environment factors. Therefore, to extend the network lifetime, a new design is needed that maintains security and considers environmental factors. This paper introduces a method to increase the energy efficiency and increase the detection rate of false reports by adjusting the security strength of the report generated at the node according to the node density and geographical location. The proposed method has the advantage that it can be applied to various security protocols based on Message Authentication Code (MAC).
