There have been various secure routing protocols proposed for mobile ad hoc networks. Most of these protocols are analyzed by two standard techniques: simulation and security analysis. There has been a lack of work related to the performance of secure routing protocols in real network testbed. In this paper, we present quantitative results for the performance comparisons between AODV and SAODV routing protocols by using a small-scale experimental testbed, which consists of 10 laptops within a 250 m by 100 m rugby field. Apart from outdoor testing, we also compare the results with those obtained via simulation and indoor emulation. The workload includes both UDP and TCP traffic. Results show that SAODV is effective in preventing routing message tampering and data dropping attacks. For outdoor experiments, we also estimate the average distance within a communication gray zone under different bit rates.
