— 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)
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)
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)
— Mobile Ad-hoc NETworks (MANETs) are a type of infrastructure-less networks that are most useful in unprepared emergencies where critical applications must be launched quickly. However, they often operate in an adverse environment where end-to-end connectivity is highly susceptible to various disruptions. Methods of adjusting the motion of existing nodes(More)
Mobile cloud computing (MCC) has recently been drawing increased attention in academia as well as industry. Content retrieval is a critical service, for many mobile cloud applications and in turns relies on other resources and tools, e.g., internal storage, content searching and sharing, etc. Previous studies have shown that conventional ICN interest query(More)
Popular ad hoc routing protocols such as DSDV and AODV use " predecessor " based forwarding, namely, the packet is forwarded to the predecessor that advertised the shortest path to destination during the last update. However, if the predecessor moves, the routing table entry becomes invalid and predecessor based forwarding fails! To overcome the stale(More)
BACKGROUND AND AIMS Current cardiovascular disease (CVD) prevention is based on diagnosis and treatment of specific disease. Little is known for high risk people with CVD at the community level. In rural China, health records of all residents were established after the recent health reforms. This study aims to describe the characters of the rural population(More)
1 Summary Network scalability is one of the critical challenges and requirements in routing protocols for ad hoc networks. This paper presents a novel scalable routing protocol called Geo-LANMAR. The proposed protocol inherits the group motion support of Landmark Routing (LANMAR) and applies the geo-routing concept to deliver packets efficiently. In this(More)
