Message Dissemination VANET Projects

Message Dissemination VANET Projects is the idea to spread useful information all the way through the network. In view of VANET that is vehicular ad hoc network shares both safety and non-safety data. In general, safety message sharing mainly acquaint with the concept of message dissemination in VANET.  

Do many Safety messages take in VANET? Yes, they are here. 

• Accident on the road lane
• Emergency vehicle stop 
• Brake failure in the vehicle 
• Vehicle crossing speed limit 
• Severe traffic warning 
• Natural disasters (earthquakes, fires and etc.)

   With attention to above all, the alert message will be by anyone. In either case, this type of message in VANET offers by IEEE 802.11p. It fact gives aid for both unicast and broadcast data over vehicles in V2V, V2I, and others. On the other hand, it allows data sharing, even though it be real with some challenges.

Critical issues identified in VANET Message Dissemination 

• Fake information by the attacker
• Untrusted vehicles 
• Delivery of the same message multiple times (i.e.) redundancy 
• Lack of connectivity due to frequent changing topology  
• Selection of less efficient forwarder  
• Delay in broadcast 
• High dense vehicles at high velocity
• Broadcast storm problem 

   In the event that the safety message broadcast will not be reliable while we ignore those issues. While it may be true, the protocol or algorithm in Message Dissemination VANET Projects must solve the issue using the below ideas. 

Key Concerns in the design of Message Dissemination Protocol

• Adaptive adjustment of beacon 
• Multi-criteria to select disseminator
• QoS and topology-aware message 
• Balanced load 
• Dynamic back-off estimation 
• Forwarder probability formulation

   The vehicles broadcast the message, but the ITS also sends alerts through intelligent traffic lights. It is important to realize that the vehicles are able to sense, and hence they detect the accident and give the reports to others. 

What are the ways to disseminate messages?

• Forwarder or relay selection
• Select next forwarder 
• Disseminate within coverage
• Cluster-based 
• Generate cluster
• Select cluster heads to disseminate
• Random 
• Disseminate to all the vehicles 
• No need for constraint estimation 
• Segment or partition-based 
• Disseminate using segment head
• Broadcast only within the segment or partition

   Prior to VANET, this idea is in three types, such as 1. Push, 2. Pull, and 3. Hybrid. But now it extends in new ways as we tell before. Still, the push is proactive that sends periodic while pull depends on demand. So far, this concept also has the issue of security, which is now in link with blockchain. All of a sudden, it is a positive way out to give security whenever a message spread in VANET.   

Want to know the Approaches in Message Dissemination VANET Projects?

Look below, 

• RPB-MD protocol
• Adaptive fuzzy 
• Data-centric approach 
• Transmit packet coding 
• VLCS with TDMA
• Game-theoretic approach
• Multi-resolution strategy
• MC-EMD, CB-EMB, and also DD-CPB
• 3P3B and so on

Growth of Message Dissemination into, 

• Internet of Vehicles and also Urban IoV
• V2X communication 
• LTE and also 5G networks 
• Software-Defined VANET 
• Edge computing (Fog) with vehicular network

   To be sure, OMNET++ is the most appropriate tool for this concept. It was then able to merge with SUMO, VEINS, MiMiX, and TranNS too. Besides, this has a special feature to aid phd projects in vanet with research topics such as traffic such as highway, urban, junction, and so on.

Other Simulators in use to Test VANET message dissemination

• Network Simulator version 2 and also 3
• Qualnet
• Matlab
• NetSim 
• Mininet 
• And many more 

   In sum, we are able to go in-depth on all the topics in this field. In brief, to explain that, we give you aid from the start. That is to say, we allot a team of those who have high skill in your topic. So that as of your need, you can discuss it with the experts as long as you need it. Next, they put up full power since you are at the opening stage so that you could conclude your topic to that end.
