Abstract:

Routing strategies in mobile ad-hoc networks (MANET) are somewhat more complex than regular routing in classic wired networks. MANET nodes need to dynamically change their routing paths in order to adapt to the changing topology and the possible interruptions caused by possible limited availability of certain nodes and links. IETF proposes different protocols and algorithms to provide the necessary flexibility. Both datalink layer (such as 6LoWPAN path definition and frame forwarding) and pure cognitive networking solutions have been evaluated by the developers of picoTCP as possibilities to provide the best design for TCP/IP over MANET in embedded systems. Developing  OLSR, AODV and 6LoWPAN routing in mesh networks of small embedded nodes has posed non-trivial challenges, particularly on the validation of the solutions.
We will briefly describe the findings of our research, some challenges we had to face during the development and how we used a real testbed to model emulators and tools to shorten the development time.
