Traffic modeling for machine type communication and its overload control by Xin JIAN, Xiao-ping ZENG, Yun-jian JIA, Jun-yi YANG, Yuan HE

“…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 wer iven out by deducing the analytical expression of Beta distribution’s moment generation function,in which the shape parameters of Beta distribut are as-sumed 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) re-shaping the inter-arrival time distribution of MTC devices; 3) segment-wise uniform back-off scheme.The Beta/M/1 mod-el and segment-wise uniform back-off scheme proposed here can be used as a preliminary model for different MTC ap-plication scenarios and serve as a fundamental traffic model and overload control method for future ubiquitous network.…”

Lateral flexure of Erebus Ice Tongue due to ocean current forcing and fast ice coupling by Rodrigo Gomez-Fell, Wolfgang Rack, Oliver J. Marsh, Heather Purdie

“…A significant correlation (0.45) between flexure and tidal currents was found when fast ice was absent. An analytical model tuned to observations suggests that even without sea ice for stabilisation, the lateral bending stresses induced by the ocean are insufficient to cause calving without additional amplifying factors.…”
