Ensuring transportation network security is one of the most daunting challenges confronting homeland security agencies today. Significant research has been dedicated to model and analyze the vulnerability of transportation systems, yet notably fewer studies propose specific strategies for deploying defensive technologies to safeguard these systems. The ultimate goal of situational awareness for prevention and rapid response remains largely unaddressed. Wireless sensors and ad hoc networks are widely regarded as a promising approach to monitor systems and enhance their security. Furthermore, the growth in smart phone usage can contribute additional relay nodes to the network connecting the deployed sensors and command center. Such sensor networks offer the potential to detect a terrorist plot before it can be executed, support effective response to emergency events, and dynamically monitor traffic flows to facilitate efficient travel within a city. This paper present a scheme which turn the deployment into a optimization to maximize the weighted coverage, and we demonstrate the approach through the simulation, the result of which clear indicates its effectiveness.
