MANET Routing Protocol in VANET

Question: Discuss about the MANET Routing Protocol in VANET. Answer: Introduction The paper depicts the strength and weakness of MANET (Mobile Ad hoc Network) routing protocol in VANET (Vehicular Ad hoc Network) in accordance to the provided article. VANET is a subclass of MANET type network. Nowadays, co friendly transportation has become one of the most overriding wireless networking protocols and VANET is one of them(Maratha) . Thus, VANET can be distinguished from other protocols by defining the strength and weakness of the real life example mentioned in the article. In real time systems several simulators come under consideration to determine the positive and negative perspectives. Strength and weakness of MANET routing protocol in VANET Strength In this article the modern approach of Intelligent Transportation System (ITS) that is able to mitigate all the issues occurred in the primitive approaches of ITS, are mentioned. In MANET all the considerable nodes are mobile and it required ad hoc type routing protocol. While reviewing the paper, other strengths are also found. These are as followed: 1. It demonstrates that the RSU are becoming expensive everyday thus, to reduce the cost effectiveness utilization of VANET protocol is adopted in vehicular communication system. 2. AODV is referred to as backtracking learning as the data packets do not get lost between the communication paths. 3. (Maratha), stated that a geographic protocol is also implemented to measure accurate GPS in order to search an exact node for data transfer between vehicles. 4. How the DSDV has comparatively less amount of disconnection than AODC and DSR and capability of the GPS to select a collision free road to avoid fluctuation during communication is also stated in this article. 5. The paper also illustrates that AODV is not costly as only the required routers are presented in its table for calculation and due to increment in AODV protocol in most cases the VANET uses it. Weakness The article is based on a particular case study and the overall protocol utilization techniques are not covered thus, the knowledge gets bounded regarding MANET in VANET protocol is the major weakness. After reviewing the paper some other weaknesses are also determined. These are as followed: 1. It mentioned that in primitive transportation systems, traffic, time wastage used to occur due to lack of emerging technologies and routing protocols of Ad hoc on demand distance vectors, DSR and DSDV of MANET were utilized in node based routing that leads to spontaneous breaking of the nodes. 2. The frequent breaking causes dynamic changes in routing that is another weak point mentioned in this article. 3. Usage of these protocols in the high level mobility ambiance causes lots of loss of datagram within the channel and loss of data packets leads to failure in sending acknowledges from the sender side that might cause long delay with a lower throughput mentioned in this article. 4. Another weakness of the paper is it stated improper evaluation of selected router causes information loss, extreme collision, and time delay. 5. In AODV the discovery of the route delay is measured to be very high and is reflected in this article. 6. As the article considered a case study thus it mentioned that DSDV is better performing in high way scenarios but it has a tendency to drop datagram during collision and if the number of nodes increases it is not efficient this is another weakness of the article. Conclusion From the overall review of this article it can be concluded that the paper presented a comparative analysis on routing protocols for Mobile and Vehicular Ad hoc Networks. It is found that the implementation of AODV routing protocol in VANET increase the performance of Intelligent Transport System than other routing protocols used in transportation. Different metric also compare the performance of the routing protocols. Finally, it can be said that in order to build a smart transportation system implementation of VANET wireless network technology is highly required in MANET to improve the performance.
