Traffic modeling for machine type communication and its overload control

Machine type communications (MTC), defined as machine to machine communication over cellular mobile network, is an integral part of future ubiquitous network and has broad application prospects and market potentials. To carry out the performance analysis of network in context of MTC applications, a Beta/M/1 queue model was proposed for modeling the network with MTC applications and its full performance analysis were given out by deducing the analytical expression of Beta distribution's moment generation function, in which the shape parameters of Beta distribution are assumed to be integer. In addition, to handle the congestion caused by mass concurrent data and signaling transmission from many MTC devices, three overload control measures were also presented, that is: 1) inter-class grouping techniques; 2) reshaping the inter-arrival time distribution of MTC devices; 3) segment-wise uniform back-off scheme. The Beta/M/1 model and segment-wise uniform back-off scheme proposed here can be used as a preliminary model for different MTC application scenarios and serve as a fundamental traffic model and overload control method for future ubiquitous network.
