 • Unicast: MANET is topology base routing protocol. There is a table of link storage information by which data is transferred from one node to other.

 • Multicast: In MANETs, information is delivered from source to destination through the multiple ways. If there is any path breaker for one way, then packet is delivered through the other ways. It is classified into the following categories:1) Geo-Cast–Based Routing Protocol: To deliver data from one node to other via multicasting approach. It works on the basis of GPS system. In VANETs, if all nodes are in the same zone, then one vehicle can send data from one node to many nodes. If one of the node moves out the zone, then nodes changes the position of the sender node according to the GPS location.2) Robust Vehicular Routing (ROVER): ROVER works same as AODV protocol. Sender node sends request to the destination node. Each node has ID, location, and table for routing. If the destination node accepts the request from sender, then it will reply back to the sender. If sender node is out of the zone, then there is no possibility of reply. After the acceptance of the data packet and reply, there will be transmission of data packet.3) Mobile Just In Time Multicasting Protocol (MOBICAST): When packet is transferred from sender to receiver through ZRP. Communication breaks down when the node slow down and faster. ZRP solves this issue by considering time into the transmission of data packet delivery and calculate the time by location of vehicle through GPS. It is flexible than ZRP and result of throughput is higher.
