Lessons gained from test beds of ad hoc networks and perspectives

摘要

Over the last few years we have deployed several ad hoc network test beds in France Telecom R&D premises. These test beds aim at understanding the behavior of ad hoc networks under realistic scenarios. They also provide accurate and understandable results for building a realistic simulation model in order to break the gap between simulation studies and reality. The current tests are limited to measures on SNR and routing protocol but present interesting results such as the instability of the network topology due to environmental constraint variation and human presence that has effect similar to node mobility on routing table states.
