“…In the past, there have been schemes and protocols for dissemination that rely on the infrastructure or on an ad-hoc network [11,12]. The review in this section focuses only on works that fall on the ad-hoc category for dissemination, which resembles a VANET.…”

Vehicular ad-hoc networks (VANETs) are mobile networks with highly dynamic contexts of operation. The design and application of context-aware systems could be critical to enhance the performance of protocols deployed in VANETs, which depend on both network and traffic conditions, to detect hostile communication environments, as well as to offer a novel way to make decisions in real-time. In this paper, we present a baseline study for the design of a context-aware system for dissemination of safety messages in VANETs. We model a realistic vehicular intersection and perform extensive simulations to evaluate two well-known dissemination mechanisms, namely the Slotted 1-persistence and the Traffic Adaptive Data Dissemination (TrAD) Protocol, with a set of parameters according to different operation scenarios. We show how the dissemination mechanisms’ performance could be improved, or worsened, by choosing a different set of parameter values. By characterizing the operation scenarios, it is possible to adequate the parameters of the dissemination mechanism with the values that work best in a given context, improving in this way the general performance of the dissemination mechanisms under study.

In Vehicular Adhoc Networks (VANETS), Data Dissemination is a challenging task. There are number of techniques, types and protocols available for disseminating the data but in order to preserve limited bandwidth and to disseminate maximum data over networks makes it more challenging. These protocols are classified as broadcasting, multicasting and geocasting based protocols. Multicasting based protocols are found to be best for conserving the bandwidth. One such protocol named Bandwidth Efficient Acknowledgment Based Multicasting Protocol (BEAM) exists that improves the performance of VANETS by reducing the number of in-network message transactions and thereby efficiently utilizing the bandwidth during an emergency situation. But this protocol may result in multicar chain collision as there is no V2V communication. So, this paper proposes a new protocol named Enhanced Bandwidth Efficient Cluster Based Multicasting Protocol (EBECM) that will overcome the limitations of existing BEAM protocol. Along with this Simulation results will show the improved performance of EBECM in terms of Throughput, PDR and Routing overhead when compared with BEAM protocol.

“…So, it becomes mandatory to have techniques or protocols for sending data packets in urban areas. And Urban Multihop broadcast (UMB) protocol is one of them that does directional broadcasting as well as broadcasting at intersections in urban areas [1]. Ad-Hoc Multihop Broadcast Protocol: In the AMB protocol, directional broadcast is same as that of UMB protocol but in case of Intersection broadcast-vehicles attempt to choose the closest vehicle to the intersection using a fully adhoc algorithm and the chosen vehicle forwards the packet to all road segments except the road segment the packet is received from [1].…”

Acknowledgment-Based Broadcast from Static to highly Mobile Protocol: In this protocol, a vehicle that receives a data packet will not forward that packet immediately rather vehicle will check if retransmissions from other neighbours already cover its whole neighbourhood in order to avoid redundancy.…”
