Safety message generation rate adaptation in LTE-based vehicular networks

Safety Message Transmission in Vehicular Communication Networks

Emerging vehicular safety applications require low latency communications and reliable packet dissemination for life saving safety messages. Significant developments have taken place over the past few years. IEEE WAVE and ISO CALM have been developed as international standards for ITS applications. Both WAVE and CALM support multichannel operations and use CSMA/CA as channel access mechanism. W...

Rapid Dissemination of Public Safety Message Flows in Vehicular Networks

—We consider a Road Side Unit (RSU) that aims to broadcast critical public safety message flows to vehicles that travel along a linear highway. The RSU is able to transmit such message flows directly to only a limited group of vehicles travelling in its close vicinity. To assure delivery of these messages to all other vehicles traveling along the highway, we make use of a Vehicular Ad Hoc Netw...

Efficient safety message dissemination methods in vehicular adhoc networks

Safety Message Power Transmission Control for Vehicular Ad hoc Networks

Problem statement: Vehicular Ad hoc Networks (VANET) is one of the most challenging research area in the field of Mobile Ad Hoc Networks. Approach: In this research we proposed a dynamic power adjustment protocol that will be used for sending the periodical safety message. (Beacon) based on the analysis of the channel status depending on the channel congestion and the power used for transmissio...

A Context Aware Rate Adaptation Algorithm for Vehicular Networks

Intelligent transport system (ITS) applications are attracting more attention both in industry and in research. However, there are still myriads of problems facing the implementation of ITS applications. In vehicular networks, issues such as rate adaptation poses a great challenge. Due to the fact that the environment in which vehicular networks operate is heavily subjected to rapid changes in ...
