Using channel characteristics for authentication in wireless sensor networks has many advantages such as low power, low computational overhead and crypto-free system. In spite of its advantages, it faces two challenges. The first challenge is the regional effects like WiFi and communication obstacles. The second challenge is that when it is applied in an environment that has human motion, it fails. These challenges cause false alarms in detection. In this paper, we introduce two mechanisms to face these challenges. The first one helps to differentiate between regional effect and malicious nodes. If the number of nodes fail in authentication in the same region exceeds certain threshold, regional effect is detected. The second mechanism is based on the idea of cooperative detection. If a node fails to authenticate with one neighbor due to human presence, it can instead authenticate with another neighbor, so it can still be trusted.
