abstract

This paper presents an effort that is aimed at addressing two challenges in the monitoring of some bridges and roads: poor wireless signal transmission and low real-world survivability of wireless sensors. A product is proposed; a prototype is designed and made to protect some off-the-shelf wireless sensors and improve their performance. The design is based on numerical simulations of the electromagnetic field including using finitedifference time-domain method. To protect the wireless sensors and all other components, basic structural analysis is exercised to obtain an enclosure design that tends to optimize the load-carrying capacity given the design constraints. All materials used for the enclosure have low electrical conductivities limiting or nullifying their negative imprint on wireless communication. Off-the-shelf components are utilized as often as possible to minimize the overall cost and expedite the manufacturing process. The problem encountered in the real-world testing of the design is presented, analyzed and solved.
