In this paper, we study the potential of using the metric of Age of Information (AoI) for enhancing delay-tolerant routing protocols.The latter have been proposed for alleviating the impact of long roundtrip time in networks operating in venus tops and blouses harsh environments, e.g., in distributed applications deployed in a desert/sparsely populated area without infrastructure, a space network, etc.

Delay-tolerant routing protocols can prevent excessive packet timer expiration, but do not provide any packet delivery time guarantee.Thus, they are unsuitable for time-sensitive applications that are more intensely desired nowadays in the next generation networking applications.By incorporating AoI into the operation of delay-tolerant routing protocols, we aim at devising routing protocols princess jasmine silhouette that can cope with both long propagation times and challenges related to time-sensitivity in packet delivery.More specifically, in this work, we modify the operation of a well-known delay-tolerant routing protocol, namely FRESH, to make AoI-based packet forwarding decisions, aiming at achieving specific delay guarantees regarding the end-to-end delivery time.

We investigate the advantages and disadvantages of such an approach compared to the traditional FRESH protocol.This work serves as a cornerstone for successfully demonstrating the potential of exploiting AoI in delay-tolerant routing and its applications.
