Wireless sensor network (WSN) popularity is increasing for a wide variety of applications, yet the integrity and confidentiality of transmitted data remains one of the major barriers to its full exploitation. In this paper, an outdoor experimental testbed of multi-hop WSN with dimension 21 m x 18 m for pipeline monitoring was developed. A light-weight symmetric cryptographic algorithm was developed to encrypt and decrypt transmitted data. A simulator running on a VB interface was also developed to test the efficiency and functionality of the developed algorithm, to monitor leakage detection in pipeline and evaluate the effectiveness of the simple cryptographic security algorithm rupture in the water pipeline testbed was simulated by opening and closing valves installed at various points of the water pipeline testbed. The effect of simulated rupture in terms of amplitude of acceleration (vibration change) was found to be proportional to the rupture location and sensor nodes location. The results generated from these simulations where implemented with the developed WSN simulator, to show how encryption and decryption of data at the different nodes are achieved.
