Large area of flooding—flooding is a routing technique used to forward packets from the source to destination during the route discovery phase or in a recovery phase. Geographic routing (also called georouting or position-based routing) is a routing principle that relies on geographic position information. Among all the flooding algorithms, GOSSIP [5] promises the least communication overhead. Flooding is a non-adaptive routing technique following this simple method − when a data packet arrives at a router, it is sent to all the outgoing links except the one it has arrived on. ... On the Second vector exchange, C comes to know that B has a path of 1 hop length to A, so C updates its routing table and indicates a path of 2 hop length. 3.4. id (1....n) & destination address now algo will calculate where packets will go. From amongst computed costs, a selection is taken minimizing the cost by using Viterbi algorithm. A Routing Algorithm is a method for determining the routing of packets in a node.
