TCP traffic round-trip delay measurements have been carried out in the Ericsson Corporate Network. Based on these data a comprehensive analysis has been performed to identify basic state changes in the network and to find the parametric distribution of the round-trip delay. The main finding of our research is that the roundtrip delay can be well approximated by a truncated normal distribution. ...

Many user applications (and the transport protocols that make them possible) require two-way communications. To assess this capability, and to achieve test system simplicity, round-trip loss measurements are frequently conducted in practice. The Two-Way Active Measurement Protocol specified in RFC 5357 establishes a round-trip loss measurement capability for the Internet. However, there is curr...

Purpose This paper investigates the usage and trust of Chinese social media in travel planning process (pre-trip, during-trip post-trip) tourists. Design/methodology/approach Through a combination structured online survey ( n = 406) follow-up interviews, research identifies diversification demand-and-supply patterns users China, as well allocation functions tools before, during after travel. Fi...

The plug-in hybrid electric vehicle (PHEV), utilizing more battery power, has become the next-generation HEV with great promise of higher fuel economy. Global optimization charge-depletion power management would be desirable. However, this has so far been hampered due the a priori nature of the trip information and the almost prohibitive computational cost of global optimization techniques such...

This study investigates replication strategies for reducing latency to desired content in a vehicular peer-to-peer network. We provide a general constrained optimization formulation for efficient replication and study it via analysis and simulations employing a discrete random walk mobility model for the vehicles. Our solution space comprises of a family of popularity based replication schemes ...

The hours of service regulations of the department of transportation severely restrict the set of feasible driver schedules. So much so that establishing whether a sequence of full truckload transportation requests, each with a dispatch window at the origin, can feasibly be executed by a driver is no longer a matter of simple forward simulation. We consider this problem and prove that the feasi...

The Design Automation and Test in Europe (DATE) conference is the main European event in the field of Computer Aided Design (CAD) and testing. This outstanding event brings together researchers, users and vendors, as well as specialists in the design, test and manufacturing of electronic circuits and systems. DATE is a unification of the main conferences in the field and was built on the succes...
