Talk:On Demand Routing

It is also a concept, not just a cisco technology, I think

From an article: "An efficient multiple-path routing protocol for ad hoc networks" by Ming-Hong Jiang, et al.:

[quote] Many routing protocols have been proposed for ad hoc networks. These routing protocols can be divided into two types, table-driven and on-demand (source-initiated).

Table driven routing protocols are based on the DBF routing protocol. They attempt to use large number of control messages to get the latest and the most complete routing information. These routing protcols require that each mobile node stores up-to-date routing information in its routing table and responds to networok topology changes py propagating update messages to all hosts in the network to maintain a consistent routing table. Typical table-driven routing protocols are destination-sequenced distance-vector routing, wireless routing protocol and cluster-head gateway switch routing.

On-demand routing protocols create routes only when they are needed. When a node wants to communicate with another node, it initiates a route-discovery procedure. Once a route has been created, it is maintained by route-maintain procedure until either the route is no longer needed or the destinationis gone. Typical on-demand routing protocols are dynamic source routing, ad hoc on-demand distance vector routing (AODV), associativity based routing, signal stability-based adaptive routing, the zone routing protocol and the temporally ordered routing algorithm.
