In this paper, the authors seek to address the problem of congestion in WSNs (Wireless Sensor Networks) by identifying the metrics that strictly relate with the philosophy and design of WSNs. From various study on WSN, the focus on experimental key performance indices is yet to be adequately addressed considering periodic event sensing. Consequently this paper proposes a congestion management scheme that will detect and overcome the congestion prior to its instantaneous occurrence called Priority Early Detection Congestion Avoidance Mechanism (PEDCAM). The main feature of the proposed algorithm is priority early detection of the congestion pre-occurrence, control optimization and buffer scheduling. With PEDCAM, a comprehensive trace file validation environment based on C/C++ OPNET Modeller was developed.
