Integrated Routing Protocol for Opportunistic Networks

TL;DR

This paper introduces an integrated routing protocol for opportunistic networks that adaptively uses context-aware or context-oblivious strategies, improving message delivery and delay regardless of context information availability.

Contribution

The novel integrated routing protocol dynamically switches between context-based and oblivious routing, enhancing performance in diverse network scenarios.

Findings

Outperforms epidemic and PROPHET in message delivery probability

Reduces message delay in both context-aware and oblivious conditions

Demonstrates adaptability to varying levels of context information availability

Abstract

In opportunistic networks the existence of a simultaneous path is not assumed to transmit a message between a sender and a receiver. Information about the context in which the users communicate is a key piece of knowledge to design efficient routing protocols in opportunistic networks. But this kind of information is not always available. When users are very isolated, context information cannot be distributed, and cannot be used for taking efficient routing decisions. In such cases, context oblivious based schemes are only way to enable communication between users. As soon as users become more social, context data spreads in the network, and context based routing becomes an efficient solution. In this paper we design an integrated routing protocol that is able to use context data as soon as it becomes available and falls back to dissemination based routing when context information is not available. Then, we provide a comparison between Epidemic and PROPHET, these are representative of context oblivious and context aware routing protocols. Our results show that integrated routing protocol is able to provide better result in term of message delivery probability and message delay in both cases when context information about users is available or not.
