“…While this mobility can create some difficulties regarding the wireless networking aspect of inter-vehicle communication, it can greatly amplify the sensing range of each sensor. In [8] and [9] we have studied the delay-tolerant connectivity of a vehicular sensor network in an urban scenario. We have defined this delay-tolerant connectivity as a function of the time interval considered.…”

Vehicular sensing is emerging as a powerful mean to collect information using the variety of sensors that equip modern vehicles. These sensors range from simple speedometers to complex video capturing systems capable of performing image recognition. The advent of connected vehicles makes such information accessible nearly in real-time and creates a sensing network with a massive reach, amplified by the inherent mobility of vehicles. In this paper we discuss several applications that rely on vehicular sensing, using sensors such as the GPS receiver, windshield cameras, or specific sensors in special vehicles, such as a taximeter in taxi cabs. We further discuss connectivity issues related to the mobility and limited wireless range of an infrastructure-less network based only on vehicular nodes.

“…Connectivity is a fundamental requirem ent for communication between nodes [15][16][17][18][19][20][21], Establishing a stable connection between nodes of MANETs is necessary for their communication. Mobility of the nodes and their communication range influence the connectivity between them.…”

“…The ^-connectivity of an ad hoc network ensures th a t each node can be reached even if any k -1 nodes are removed from the network [19,21]. Several theoretical and some sim ulation-based analysis related to connectivity, mainly based on RWP mobility model, have been reported in the literature [15][16][17]19,21,52,[64][65][66]. Our stu d y on connectivity uses simulations on DGM models, in comparison with th e RWP mobility model.…”

“…Based on [34], th e pa per [66] The authors in [17] contrasted connectivity profiles obtained from RW P and M an hattan grid model against the profiles extracted from a realistic traffic sim ulator, and showed th a t widely used M ANET mobility models are inadequate to capture th e spe cific properties of VANETs in urban environments. They used average node degree and transitive connectivity metrics and highlighted multi-hop connectivity in delay tolerant applications in sparse networks.…”
