In current research on mobile ad-hoc networks, protocol evaluation is always needed. However, building real test-beds are costly, and sometimes infeasible, especially for large-scale mobile ad-hoc networks. Therefore, simulation systems are provided. Unfortunately, exiting simulation systems have obvious defects. They can hardly support scalability or real-time simultaneously, neither changeable network nodes. To remedy these problems, we propose a test system named ManTS in this paper. With distributed architecture and some novel mechanisms, such as Direct Transmission and Virtual Application Traffic, etc., ManTS is able to build testbeds for large-scale mobile ad-hoc networks and guarantee real-time at the same time, and it also supports dynamic enrolment of network nodes. Furthermore, IP or upper layer protocols and applications implemented on Linux can run on ManTS without any modification.
