Communication in machine-to-machine environments

It has been estimated that by the end of 2020 there will be 50 billion connected devices in Machine-to-Machine (M2M) networks. Such projections should encourage us to deal with the corresponding problems in heterogeneous M2M systems. First of all, devices can communicate through different access technologies (e.g. wireline, 2G/3G, WiFi, Bluetooth) and their communication can be classified as direct or indirect, internal or external. In this paper we explain differences between those types of communication and propose a new identification scheme that allows M2M devices to establish communication in every possible way. Secondly, there is a problem of device hardware and software diversity. To over-come this problem, we propose the usage of the Open Service Gateway Initiative (OSGi) framework.
