(Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

Even though VANET is considered as a type of MANET, it has its own particular features that make it different from MANET. These characteristics include: 1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m. 2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network…
