Mar 11, 2019 although centrality is widely used to differentiate the importance of nodes for socialaware routing in mobile opportunistic networks mons, it is destination agnostic since such metrics are usually measured without destination information. A pbr bases routing decisions for the data packets on parameters such as source ip address, source port, destination ip address, destination port, protocol, and source mac address. Dynamic routing, also called adaptive routing, is a process where a router can forward data via a different route or given destination based on the current conditions of the communication circuits within a system.
