Urban VANETs and hidden terminals: Evaluation through a realistic urban grid propagation model

Despite the large number of active field-trials, network simulations still play a vital role in the development and validation of new protocols for vehicular networks. This role still motivates the improvement of simulation tools, especially in terms of realism, so to yield accurate results.…

SCB: Store-Carry-Broadcast Scheme for Message Dissemination in Sparse VANET

To take on challenges of communication in sparse VANET, we propose a Store-Carry-Broadcast (SCB) scheme to assist message dissemination by broadcasting over a specific road segment instead of a single vehicle. In the SCB scheme, an opposite vehicle helps to…

Endpoint protection zone (EPZ): Protecting LBS user location privacy against deanonymization and collusion in vehicular networks

In vehicular networks when map databases may be used to deanonymize user locations, we propose location based services, LBSs, be designed so that LBS users are grouped by spatial location, into endpoint protection zones, EPZs. Users in the same EPZ would share login…

SRB: A Selective Reliable Broadcast protocol for safety applications in VANETs

In this paper we present a novel vehicular communication protocol, which aims to reduce the effect of broadcast storm problem in VANETs. When the traffic density is above a certain value (e.g., when vehicles are in congested traffic scenarios), one of the…

An efficient data aggregation algorithm in delay tolerant vehicular networks

We are interested in delay-constrained data aggregation in delay tolerant vehicular networks, in which contact opportunities are usually scarce and thus become critical resources. Data aggregation has been recognized as an effective technique for reducing communication cost while obtaining useful aggregated information.…

A Message Suppression Controller for Vehicular Delay Tolerant Networking

In this paper, we propose a Message Suppression Controller (MSC) for Vehicular Delay TolerantNetworking (VDTN) under highly stressed environment. The simulations for two scenarios are conducted considering obstacles (buildings), where MSC with Road side units (MSCRs) are present or not present. We consider…

A semantic hot replication of self organization software platform Router

There are various unstable situations in IoT environments due to the characteristics of wireless local connections, the faults in IoT devices, and the IoT devices crowd at a unit space. To construct a more stable IoT environment for IoT services, the IoT Routers for the IoT service overlay networks should be constructed solidly first.…
