Content Distribution Strategies in Opportunistic Networks

TL;DR

This paper investigates content distribution in opportunistic networks, analyzing how seeder numbers and coding strategies impact content retrieval rates among subscribers.

Contribution

It introduces a mechanism for content dissemination using opportunistic contacts and evaluates the effects of seeding and coding strategies on retrieval efficiency.

Findings

Higher number of seeders improves content retrieval rates.

Coding strategies like Network Coding and Erasure Coding enhance dissemination efficiency.

Epidemic Routing and Flooding are effective in content distribution.

Abstract

This paper describes a mechanism for content distribution through opportunistic contacts between subscribers. A subset of subscribers in the network are seeded with the content. The remaining subscribers obtain the information through opportunistic contact with a user carrying the updated content. We study how the rate of content retrieval by subscribers is affected by the number of initial seeders in the network. We also study the rate of content retrieval by the subscribers under coding strategies (Network Coding, Erasure Coding) and under Flooding, Epidemic Routing.
