Adaptability to highly dynamic networks is the main advantage of AODV. On the other hand, the node may …show more content…
It performs three functions; route creation; route maintenance; route erasure. Nodes use height metric to establish DAG to the destination. It uses analogous link reversal and the route repair methods as in LMR, and the formation of a DAGs, that is analogous to the query/ reply process used in LMR. When a node moves the DAG, route was broken and route maintenance is to reestablish the route to the destination. Route erasure phase involves broadcasting a clear packet to entire network to remove invalid routes [1]. The TORA protocol is required to maintain unique ID of the node; reflection indicator bit; propagation ordering parameter; logical time of link
