Application of wireless sensor network to make transportation fleet information systems smart

Traffic signs are tools to control and regulate movement, on streets and crossings. These signs individually play their own essential role in reducing accidents and securing traffic. Unfortunately, thieves steal these signs on suitable occasions to sell them as scrape in black market. Wireless sensor systems are of desirable features including independence, being capable of expanding in remote and inconsistent places. They may be assigned such operations as supervising traffic signs. This essay aims at study of some hierarchical routing protocols or static cluster, introducing a new protocol through which we focus on clustering special nodes having no-battery in contrast to ordinary nodes. The result is to obtain network more stability and optimal energy consumption. The new protocol was tested on real characteristics of more than 600 traffic signs in the city of Hamedan, run in MTALAB software. The findings are examined here.
