Emergency Broadcast Protocol for Inter-Vehicle Communications

Modeling and Analysis for Emergency Messaging Delay in Vehicular Ad Hoc Networks

“…This concept is sometimes used for location discovery process [26]. Cluster based broadcasting is used in BROADCOMM with enhanced message prioritization done by CH [27]. When a CH has more than one message to forward, it decides which message to be sent first.…”

“…In order to overcome the limitations of flooding and increase the scalability of the broadcasting, only particular nodes are chosen to relay the message. Many techniques have been proposed in literature for choosing the relay nodes, one of which makes use of the clustered network infrastructure where the backbone, consisting of cluster heads (CHs) and gateways, is used to relay messages [6,27].…”

The Role of Ontologies in Enabling Dynamic Interoperability

“…These rules enable to deduce the difference that lies between the packet formats P 1 and P 2 . For instance, let us assume P 1 to be a BBR packet [5] (designed for performing Broadcast-based routing) and P 2 to be a Broadcomm [7] packet (designed for performing cluster-based routing). At this stage, both packets P 1 and P 2 have already been classified under the appropriate routing scheme by the ontology.…”

Abiding Geocast for Warning Message Dissemination in Vehicular Ad Hoc Networks

“…Another approach for safety applications makes use of simple directed broadcast-based communication without considering the efficiency of the message dissemination mode [5]. An emergency message dissemination protocol for IVC divides the highway into virtual cells [6], which move as the vehicles move. Another cluster-based protocol disseminates traffic and road conditions by using a combination of MANET and DTN (Delay Tolerant Networking) methodologies [7].…”
