Modeling and simulating wireless sensor transportation monitoring network

We have proposed a new wireless transportation monitoring scheme based on wireless sensor network (WSN), namely wireless sensor transportation monitoring network (WSTMN), which differs from some old wired schemes greatly. As a novel information acquisition technology, WSN has many advantages that help to improve the performance of transportation monitoring system. We simulated WSTMN in NS2, in which some new functions are extended. Some simulating experiments are designed to optimize these important parameters including energy consumption of sensor nodes, network density and data sensing rate, so as to optimize the WSTMN model. The WSTMN system is proven to be feasible with low system cost, low energy consumption and high efficiency. It prefers obviously to the old systems on the aspects of real-time control, enormous data computation and immunity to disturbances
