Heterogeneous wireless sensor network consists of sensor nodes with different ability. In this paper, developing a secured environment for detecting malicious nodes in a heterogeneous wireless sensor network. Different abilities such as different computing power and sensing range. With a probability model to analyze the best redundancy level which using path redundancy and source redundancy. The concept of this redundancy management is to exploit the tradeoff between energy consumption within the gain reliability, timeless and security to maximize the system useful lifetime.
