  • Title: muXer: Efficient network selection in heterogeneous communication scenarios using arbitration
  • Abstract: The usage of mobile internet has steadily increased over the past years. The devices used for accessing the internet often feature multiple communication technologies such as GPRS, UMTS/CDMA, LTE and Wireless LAN. Moreover, technologies over short distances like Bluetooth or even NFC allow for the deployment of hop-by-hop networks using protocols as for example the Bundle Protocol for Delay Tolerant Networks. Within the muXer project an architecture was developed to facilitate a more efficient usage of these heterogeneous networks. Instead of using a single network that all applications share, muXer allows for the parallel utilization of multiple networks, network bundles and the proactive delaying of applications as possible decisions when assigning applications to networks. With respect to these options the Global Arbitration Process (GAP) was implemented within my Bachelor Thesis that schedules applications for networks while simultaneously meeting application and user requirements. GAP was compared to other network selection strategies and a clear efficiency gain was observed.

    As the muXer project is one starting point for the research within A2, a first outlook on the applicability of its results in the CCC project is also given.
