Machine-to-Machine Applications meet Opportunistic Communications: Friends or Foes?

James Gross (KTH, Sweden)

Abstract. Over the next decade forecasts predict a rapid increase in data traffic and communication devices. The majority of this growth is assumed to stem from control-type applications deployed at massive scale which will lead to significant efficiency gains in digitized societies. Anticipating these gains, different research communities have started to investigate the challenges of these novel applications. The understanding of these challenges from the point of view of the different communities run under different 'buzz words' like Internet-of-Things, Cyber-Physical Systems, Smart Systems and Machine-to-Machine Communications, but all of these address the same fundamental change ahead of us. From a networking point of view, one of the most urgent challenges of these novel applications are their requirements with respect to reliable real-time data services combined with the huge capacity demands (while other important challenges relate to energy-efficiency, security and privacy, but are not addressed in this talk). In order to meet this challenge, we discuss in this talk opportunistic communication techniques at the link and network layer. In particular, we focus on dynamic spectrum access as key enabler to meet the capacity demands of machine-to-machine applications. This raises questions regarding the reliability and potential delay bounds that can be guaranteed under a given primary system traffic load. In contrast to intuition, we show that indeed bounds for reliability and delay can be derived using a model-checking approach known from software systems. This raises the question regarding other bounds and insights that can be found at the intersection of opportunistic networking and machine-to-machine applications.
