摘要

Wireless communication technology shows great promise as an alternative to traditional fiber optics and telephony communications solutions in traffic management applications. This paper presents a field performance evaluation of wireless communication between two adjacent nodes that represent communications between traffic sensors or traffic sensors and controllers. This paper also provides insights into the performance evaluation of wireless sensor network in a highway environment. This insight will contribute to a better understanding of network design and deployment issues of wireless sensor network for use in future traffic management applications. The experimental setup included two wireless access points (wireless routers) connected to two laptops placed at different locations along a highway section in Clemson, South Carolina. The roadside was covered with high density vegetation with no clear line of sight between these two sensor nodes. The IPERF network testing tool was used to measure the throughput of wireless communication between these two adjacent nodes under different communication protocols and wireless transmission powers. Results indicated a distinct relationship between the wireless connection performances and the communications transmission power in both Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
