Traffic Measurement for Big Network Data (Wireless Networks) by Shigang Chen,Min Chen,Qingjun Xiao

By Shigang Chen,Min Chen,Qingjun Xiao

This booklet provides numerous compact and quickly equipment for on-line site visitors size of massive community information. It describes demanding situations of on-line site visitors size, discusses the country of the sphere, and gives an summary of the capability suggestions to significant problems.
The authors introduce the matter of per-flow measurement size for giant community facts and current a quick and scalable counter structure, referred to as Counter Tree, which leverages a two-dimensional counter sharing scheme to accomplish much better reminiscence potency and considerably expand estimation range. 
Unlike conventional techniques to cardinality estimation difficulties that allocate a separated info constitution (called estimator) for every circulate, this ebook takes a special layout course through viewing the entire flows jointly as a complete: every one circulation is allotted with a digital estimator, and those digital estimators percentage a typical reminiscence area. A framework of digital estimators is designed to use the assumption of sharing to an array of cardinality estimation ideas, attaining much better reminiscence potency than the simplest current work. 
To finish, the authors talk about power unfold estimation in high-speed networks. they provide a compact info constitution referred to as multi-virtual bitmap, that may estimate the cardinality of the intersection of an arbitrary variety of units. utilizing multi-virtual bitmaps, an implementation which may convey excessive estimation accuracy below a truly tight reminiscence house is presented. 
The result of those experiments will shock either execs within the box and advanced-level scholars drawn to the subject. by means of supplying either an summary and the result of particular experiments, this publication comes in handy for these new to on-line site visitors size and specialists at the topic.

Optimal Mobile Sensing and Actuation Policies in Cyber-physical Systems

A winning cyber-physical approach, a fancy interweaving of and software program with a few a part of the actual atmosphere, depends upon right id of the, usually pre-existing, actual aspect. A bespoke “cyber” a part of the method may perhaps then be designed from scratch. optimum cellular Sensing and Actuation options in Cyber-physical platforms specializes in distributed-parameter structures the dynamics of which might be modelled with partial differential equations.

Cognitive Virtual Network Operator Games (SpringerBriefs in Computer Science)

This SpringerBrief presents an outline of cognitive cellular digital community operator’s (C-MVNO) judgements less than funding flexibility, provide uncertainty, and marketplace pageant in cognitive radio networks. this can be a new learn quarter on the nexus of cognitive radio engineering and microeconomics. The authors specialise in an operator’s joint spectrum funding and repair pricing judgements.

Cloud Networking for Big Data (Wireless Networks)

This e-book introduces uncomplicated mammoth info processing paradigms for batch info and streaming data.  consultant programming frameworks also are awarded, in addition to software program outlined networking (SDN) and community functionality virtualization (NFV) applied sciences as key cloud networking applied sciences. The authors illustrate that SDN and NFV might be utilized to profit the large facts processing by means of providing a cloud networking framework.
