Broadcasting Mechanism In Vanets For Successful Transmission: A Review

Ad hoc network is a part of wireless networking. MANETs and VANETs fall under the category of ad hoc networks. The MANET is the mobile ad hoc networks in which the nodes are self-organizing. The VANETs are also a type of ad hoc networks, but it operates on vehicular nodes such as cars, etc. IN this the communication between vehicular nodes are done by using the concept of broadcasting or dissemination. The term safety message dissemination or broadcasting refers to the sending a notification to all of the nodes in the network simultaneously. But broadcasting also has some issues like it can lead to broadcast storm, redundancy of messages, delay in message delivery, network traffic, etc. This study provides a brief introduction to the concept of ad hoc networks, MANETs and VANETS. The various broadcasting types are also represented in this paper. An overview of the work that had been done under this field by various researchers is also described in this.
