The development process for new WMN protocols and architectures is typically split into evaluation by network simulation and testing of a prototype in a test-bed. Testing in simulation often requires the developer to write software that is not directly portable to test-beds, whereas pure prototype testing on real hardware is time consuming and expensive. Irrepressible external interferences can occur, which make debugging difficult. Moreover, the test-bed usually supports only a limited number of test topologies and sites. Finally, mobility tests are impractical. Therefore, we propose VirtualMesh as a novel testing architecture, which can be used before evaluating in a real test-bed. It provides instruments to test the real communication software, including the network stack inside a controlled environment. VirtualMesh has been implemented by capturing real traffic through a virtual interface at the mesh nodes. The traffic is then redirected to the network simulator OMNeT++. In our experiments, VirtualMesh has proven to be scalable, to have minimal influence on throughput and to introduce only negligible delays (less than 0.4 ms per hop). Hence, it is a valuable tool for protocol and application developers to test their software prior to the final deployment.<\/jats:p>","DOI":"10.1177\/0037549710373909","type":"journal-article","created":{"date-parts":[[2010,7,2]],"date-time":"2010-07-02T20:54:53Z","timestamp":1278104093000},"page":"66-81","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["VirtualMesh:
