— Vehicular sensor networks are emerging as a new network paradigm of primary relevance, especially for proac-tively gathering monitoring information in urban environments. Vehicles typically have no strict constraints on processing power and storage capabilities. notification to drivers or police agents). In this novel and challenging mobile environment,(More)
The mobility model is one of the most important factors in the performance evaluation of a mobile ad hoc network (MANET). Traditionally, the random waypoint mobility model has been used to model the node mobility, where the movement of one node is modeled as independent from all others. However, in reality, especially in large scale military scenarios,(More)
The delivery of service differentiation in mobile ad hoc networks presents a number of technical challenges because of the inherent constraints due to the dynamic nature of these environments, such as limited bandwidth and energy capacity. This paper proposes a Cross-Layer Architecture for implementing DiffServ (CLAD) in IEEE 802.11 based mobile ad hoc(More)
In this paper we study the use of vehicles as sensors in a " vehicular sensor network, " a new network paradigm that is critical for gathering valuable information in urban environments. In a vehicular sensor network, each vehicle is responsible for sensing one or more events, routing messages to other vehicles or Infostations and processing sensed data.(More)
Nowadays, inter-domain routing for MANETs draws increasing attention because of military and vehicular applications. The challenges in wireless, mobile inter-domain routing include dynamic network topology, intermittent connectivity, and routing protocol heterogeneity. The existing Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol(More)
OBJECTIVE To investigate the clinical and molecular characteristics of spinocerebellar ataxia type 7 (SCA7) in Chinese kindreds. BACKGROUND Spinocerebellar ataxia type 7 is caused by the expansion of an unstable CAG repeat in the first exon of the SCA7 gene. METHODS Clinical and related examinations were performed in all affected or at-risk individuals(More)
The emergence of the H7N9 influenza virus in humans in Eastern China has raised concerns that a new influenza pandemic could occur. Here, we used a ferret model to evaluate the infectivity and transmissibility of A/Shanghai/2/2013 (SH2), a human H7N9 virus isolate. This virus replicated in the upper and lower respiratory tracts of the ferrets and was shed(More)
Vehicle communications are becoming a reality, driven by navigation safety requirements and by the investments of car manufacturers and Public Transport Authorities. As a consequence many of the essential vehicle grid components (radios, Access Points, spectrum, standards, etc.) will soon be in place (and paid for) paving the way to unlimited opportunities(More)
