Objective 1: To design an integrated operator-managed offloading system.

The MOTO system design integrates offloading within the 3GPP (3G/4G) and wireless broadband Internet infrastructures and standards. This new design adds complementary functions for mobile terminal management, trust, flow and session management.

Objective 2: To design combined offloading algorithms.

Offloading takes advantage opportunistically both of AP connectivity and terminal-to-terminal communication opportunities. The algorithms will support heterogeneous classes of services, including time-constrained flows in unicast or multicast modes, to increase overall capacity of the system.

Objective 3: To characterise the capacity benefits of the system.

Theoretical studies will take into account mobility patterns, traffic features, and green savings constraints that are typical of the use cases identified in the project (home, smart city, vehicular).

Objective 4: To perform fine-grained large scale evaluation.

The MOTO project will contribute to the development of an open source offloading simulation library within the ns3 simulation environment; it will include both infrastructure components (LTE and Wi- Fi) and terminal-to-terminal protocols. This platform will be used to perform large-scale evaluation of the offloading algorithms in terms of coverage, number of radio nodes and traffic patterns.

Objective 5: To carry out integrated prototyping and trials.

Technical feasibility and user acceptance of the system will be evaluated in the project. Partners’ test platforms covering 3G/4G and Wi-Fi infrastructures, complemented with smartphone offloading application modules will be used to implement the key mechanisms of the offloading solution (terminal management, trust maintenance, offloading control and architecture integration.
