Beyond Traditional DTN Routing: Social Networks for Opportunistic Communication

TL;DR

This paper reviews the evolution of routing protocols in intermittently connected ad hoc networks, emphasizing the shift towards social-based routing and the importance of multi-objective performance evaluation.

Contribution

It provides a comprehensive survey of social-based routing protocols and highlights the need for multi-objective performance tradeoff analysis.

Findings

Classification of routing protocols based on network graph used

Identification of performance tradeoffs in social-based routing

Highlighting the trend towards social network-inspired routing

Abstract

This article examines the evolution of routing protocols for intermittently connected ad hoc networks and discusses the trend toward social-based routing protocols. A survey of current routing solutions is presented, where routing protocols for opportunistic networks are classified based on the network graph employed. The need to capture performance tradeoffs from a multi-objective perspective is highlighted.
