An Opportunistic Network (OppNet) is a unique type of wireless network that emerges as a specialized case, derived from Delay Tolerant Networks (DTNs) and Mobile Adhoc Networks (MANETs). It is distinguished by its long network partitioning and intermittent connectivity. Traditional routing principles, based on ‘store and forward’ are less effective for OppNets due to their intermittent nature of connectivity. As a result, store-carry-forward-based opportunistic routing algorithms are employed in such networks. In ‘store and forward’ technique the data is briefly buffered before forwarding but in store-carry-forward routing, the node itself carry the data during its movement and then forwards to another suitable node. In this article we have shown that the number of wireless interface is the key attribute for enhanced deliverability and reduced delivery delay in OppNets. The fewer number of nodes carrying more number of interfaces might yield better delivery probability with smaller latency. A post disaster management scenario has been taken as a case study and the proposition has been validated for different environments with different number of nodes and interfaces in different mobility models in a simulated framework. The framework employed four benchmark opportunistic routing algorithms to obtain the results. The results are analysed to reveal that less number of rescue workers can disseminate and deliver equal or more emergency data with similar degree of reliability.
