E x p e r i m e n t i n g with an A d Hoc Wireless N e t w o r k on Campus: Insights and Experiences* C.-K. Toh, Richard Chen, M i n a r Delwar, and Donald School of Electrical and C o m p u t e r Engineering Georgia Institute of Technology Allen Abstract Ad hoc wireless networks are new communication networks that can be dynamically formed and deformed onthe-fly, anytime and anywhere. User data is routed with the help of an ad hoc mobile routing protocol. Before the deployment of ad hoc mobile services, the communication performance of such networks has to be evaluated to demonstrate the practicality limits based on today's hardware and innovative communication software. This paper describes the realization of an ad hoc wireless testbed and the various experimental field trials performed on campus. In particular, throughput, endto-end delay, route discovery time, and the impact of varying source packet size and beaconing intervals are examined. Motivation several factors and simulations do not usually account for all of them. Some may use nominal values or assume ideal channel conditions. Moreover, some are highly complexed and may not
