Mobility management is one of the most challenging research issues for vehicular networks to support a variety of intelligent transportation system (ITS) applications. The traditional mobility management schemes for Internet and mobile ad hoc network (MANET) cannot meet the requirements of vehicular networks, and the performance degrades severely due to the unique characteristics of vehicular n...

With the explosion of wireless technologies, variable types of mobility are presented. To provide seamless communication and mobility management, IP based mobility management protocols are proposed. One of them, to provide inter/intra/inner vehicle communication, the vehicles’ mobility management is studied that called VANET (vehicular ad hoc network). However, the mobility of vehicular results...

We use a stochastic frontier approach to study the effects of political and regulatory institutions on aggregate productivity in 39 countries from 1975 to 1990. We show that technical efficiency is positively related to policies supporting laissez-faire and political structures that promote policy stability. Moreover, models of technical efficiency incorporating both measures perform better tha...

Mobility management is a challenging research area for vehicular networks to provide a variety of Intelligent Transportation System (ITS) applications. Traditional mobility management schemes for MANET are not applicable to vehicular networks because of their distinguished mobility characteristics. Providing uninterrupted service to the mobile nodes in vehicular networks is a major concern for ...

This article introduces MLPOST, an OCaml library for scientific drawing. It is based on METAPOST, which allows inclusion of LTEX fragments. OCaml is an appealing alternative to LTEX macro languages, dedicated languages and even to graphic tools. In particular, MLPOST users benefit from OCaml’s expressiveness and static typing. Finally, MLPOST features a declarative style, which differs from the...

Electric scooter sharing (e-scooter sharing) is a new urban micro-mobility service that expected to shape individual mobility. The introduction of e-scooter systems poses challenging questions for cities and transportation planners regarding their effects on system. This study addresses the question concerning strategies which are applied in different operation areas Germany. An interview with ...

Cellular networks have been hierarchical so that mobility management have primarily been deployed in a centralized architecture. More flattened network architecture for the mobile Internet is anticipated to meet the needs of rapidly increasing traffic from the mobile users and to reduce cost in the core network. Distributing the mobility management functions as opposed to centralizing them at t...
