Advances in the field of wireless sensors in particular and machine-to-machine communication in general are converging into the Internet of Things (IoT). Real and virtual 'things' will create a pervasive information space that will hold vast amounts of data. The challenge is to give mobile users an on-demand access to this space, to discover and gather data dynamically from available sensors in the surroundings and enable collaboration by allowing the sharing of own data. Open M2M Data is a new paradigm in usage and delivery of (machine) data. The information space described above will be made accessible on-demand by bringing device-to-device (D2D) and machine type communication (MTC) together and introducing Linked Data principles into the machine-to-machine (M2M) platforms

The provisioning of Quality-of-Service (QoS) with interworking between heterogeneous mobile environments will be of vital importance for the future success of mobile telecommunications. As each network technology has its own distinct QoS mechanism, it becomes essential to support interworking methods between different QoS technologies, in order to guarantee end-to-end QoS in heterogeneous networks. This paper investigates the interworking between Differentiated Service (DiffServ) core networks and the IEEE 802.11e QoS-enabled Wireless LAN (WLAN). An interworking framework is proposed, in addition to a mapping scheme from the DiffServ Per-Hob Behaviors (PHBs) to the 802.11e Enhanced Distributed Coordinated Access (EDCA) Access Categories (AC). The interworking framework is evaluated by means of simulation demonstrating the conformance of 802.11e EDCA to DiffServ PHBs in an end-to-end architecture.
