  • The DYMO routing Protocol in VANET scenarios
    IEEE Vehicular Technology Conference, 2007
    Co-Authors: Christoph Sommer, Falko Dressler
    Abstract:

    Coupling Vehicular Ad Hoc Networks (VANETs) with wired networks such as the Internet via access points creates a difficult mix of highly mobile nodes and a static infrastructure. In order to evaluate the performance of typical ad hoc routing Protocols-in particular, we used Dynamic MANET On Demand (DYMO)-in such VANET scenarios, we combined microsimulation of road traffic and event-driven network simulation. Thus, we were able to analyze Protocols of the Internet Protocol Suite in VANET scenarios with highly accurate mobility models. Varying parameters of DYMO for a multitude of traffic and communication scenarios helped point out approaches for improving the overall performance and revealed problems with the deployment. It could be shown that in realistic scenarios, even for medium densities of active nodes and low network load, overload behavior leads to a drastic decrease of the perceived network quality. Cross-layer optimization of transport and routing Protocols therefore seems highly advisable.

  • connecting wireless sensornets with tcp ip networks
    Wired Wireless Internet Communications, 2004
    Co-Authors: Juan Alonso, Hartmut Ritter, Adam Dunkels, Thiemo Voigt, Jochen Schiller
    Abstract:

    Wireless sensor networks are based on the collaborative efforts of many small wireless sensor nodes, which collectively are able to form networks through which sensor information can be gathered. Such networks usually cannot operate in complete isolation, but must be connected to an external network through which monitoring and controlling entities can reach the sensornet. As TCP/IP, the Internet Protocol Suite, has become the de-facto standard for large-scale networking, it is interesting to be able to connect sensornets to TCP/IP networks. In this paper, we discuss three different ways to connect sensor networks with TCP/IP networks: proxy architectures, DTN overlays, and TCP/IP for sensor networks. We conclude that the methods are in some senses orthogonal and that combinations are possible, but that TCP/IP for sensor networks currently has a number of issues that require further research before TCP/IP can be a viable Protocol family for sensor networking.
