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(More)
The evolution of M2M (Machine-to-Machine) systems is gaining momentum in recent years. Ubiquitous wireless and wireline connectivity, and declining prices of communication modules are the main drivers of such a positive trend. While the potential market opportunities for M2M are immense, there are still many open issues: global market and standards(More)
—This paper tackles the problem of Quality-of-Service (QoS) in heterogeneous Machine-to-Machine (M2M) systems. The concern for QoS guaranties has been widely expressed in the past for both wired and wireless networks. However, only recently when these two types of networks have converged into one, thus making one huge heterogeneous system called M2M, new(More)
This paper explores the convergence of Machine-to-Machine (M2M) networks with Network-Centric Operations (NCO). An overview of the M2M communication paradigm and current standardization efforts regarding architecture are given. It includes an overview of the network-centric networking and analyses the idea of implementing NCO approach to achieve situational(More)
