Opportunistic networks are one of the most challenging area of interest MANETs. Here nodes communicate with each other when they get opportunity because path joining two mobile nodes never exists. Again nodes do not contain any knowledge about the network terminology. If they want to deliver message to the destination the routes are built dynamically furthermore, nodes are not having or possess any knowledge about the network terminology and any intermediate node selected as a next hop which brings the message closer up to the destination.
