Multi-hop vehicle-to-vehicle communication is useful for supporting many vehicular applications that provide drivers with safety and convenience. Developing multi-hop communication in vehicular ad hoc networks (VANET) is a challenging problem due to the rapidly changing topology and frequent network disconnections, which cause failure or inefficiency in traditional ad hoc routing protocols. We ...

In this paper, to realize the low delay and high throughput route discovery in multi-rate ad hoc networks, we propose a novel ondemand routing using signal strength, called signal strength aware routing (SSR). SSR is based on the on-demand routing with the route request (RREQ) and route reply (RREP) procedure. In SSR, a node measures the signal strength of a received RREQ, and calculate the app...

In multi-hop wireless networks, communication quality depends on the route from a source to a destination. In this paper, we consider a one-dimensional multi-hop wireless network where nodes are distributed randomly and theoretically analyze the relation between communication quality and routing policy using a measure called the Expected Transmission Count (ETX), which is the predicted number o...

While it is obvious that transmission without route reservation is suitable for a wired data network such as Internet, it is not clear whether this is true in the case of ad hoc wireless networks. To the best of our knowledge, this has not been studied in the literature. In this paper, we investigate the performance of two switching paradigms: reservation-based (RB) and non-reservation based (N...

One of the most important issues related to public health is parasitic diseases. Many diseases are zoonotic, emerging or re-emerging zoonoses, prevalent and difficult to control [1]. Some of these diseases such as leishmaniasis, malaria, Chagas disease and so on are vectorborne causing by pathogens transmitted by arthropods [2-4]. Some others are foodor water-borne so that contaminated food or ...

BACKGROUND The spread of infectious diseases in wildlife populations is influenced by patterns of between-host contacts. Habitat "hotspots"--places attracting a large numbers of individuals or social groups--can significantly alter contact patterns and, hence, disease propagation. Research on the importance of habitat hotspots in wildlife epidemiology has primarily focused on how inter-individu...

In southwestern Alberta, interactions between beef cattle and free-ranging elk (Cervus elaphus) may provide opportunities for pathogen transmission. To assess the importance of the transmission route on the potential for interspecies transmission, we conducted a cross-sectional study on four endemic livestock pathogens with three different transmission routes: Bovine Viral Diarrhea Virus and Bo...

There are numerous research challenges to develop safety or non-safety applications in vehicular ad hoc networks (VANETs). One of the critical issues consists in designing a scheme that solves the local maximum problem, reduces contention phase, increases the route lifetime and reduces the frequent path disruptions caused by high mobility of vehicles. Existing schemes do not take into considera...

Broadcast is the process of sending amessage fromone node to all other nodes in an ad hoc network. It is a fundamental operation for communication in ad hoc networks as it allows for the update of network information and route discovery as well as other operations. The chapter presents a comprehensive review and analysis of existing localized solutions on broadcast, where only local knowledge i...
