This mechanism is the expanding ring search technique. Using this method, the source begins its search with a TTL equal to TTL_START and defines a time, RING_TRAVERSAL_TIME, at the end of which it expects to receive an RREP response. If this time passes and the source has still not received a reply, TTL is increased by one step, TTL_INCREMENT. This is repeated as many times as necessary until TTL reaches a threshold TTL_THRESHOLD at which the value of TTL is equal to the diameter of the network (NET_DIAMETER).
In this way, the problem of routing loops is resolved. DSDV has, however, the disadvantage of requiring regular updates to routing tables, which reduces the efficient bandwidth. Moreover, DSDV is not adapted to large networks. In the absence of specifications, there are no commercial implementations of this protocol. 2. Optimized link-state routing protocol Where DSDV is an adaptation of distance-vector routing protocols for MANETs, OLSR is the equivalent adaptation of a link-state routing protocol.
1. Distance-vector routing protocols In routing protocols of this type, each node in the network sends its routing table to its neighbors. e. a timeout) or when an update is triggered by topological modifications. Upon receiving a neighboring node’s routing table, a routing node uses the information to update its own routing table. For example, if a router A sends its routing table to a neighbor B and an entry in A’s table indicates that another node X is within two hops of A, B will update its table to show that node X can be reached by B via node A in two hops.
