Performance evaluations of multi-hop ad hoc network routing protocols have been primarily conducted through analytic and simulation-based studies, which frequently fail to accurately predict real-world performance and behavior. One reason for this is the challenge in developing low cost, representative test beds with the degree of flexibility and mobility required. The authors have developed a Portable Wireless Ad hoc Node (PWAN) device which establishes multi-hop routes using the OLSR routing protocol. The PWAN's performance has been investigated using two test bed configurations to evaluate its capacity under conditions of high node density in a short-range, multi-hop environment. Their results illustrate that such networks are capable of providing high quality connections when traffic density is low.
