TLDR
It is demonstrated that appropriate utilization of place as a resource can increase network performance and decrease the load on nodes which are popular because of their location rather than their mobility pattern.Abstract:
The growth of wireless devices with short-range communications capabilities is making research into Pocket Switched Networks (PSN)s more appealing. While some recent research has investigated the role of location in predicting the mobility patterns of autonomous agents within PSNs, little attention has been paid to the location as a resource itself. In this paper we investigate the potential for stationary nodes, acting as relay stations for mobile agents in PSNs. Using empirical datasets, we demonstrate that appropriate utilization of place as a resource can increase network performance and decrease the load on nodes which are popular because of their location rather than their mobility pattern.read more

Community-based forwarding for low-capacity pocket switched networks
TL;DR: An improvement to BUBBLE, called Community-Based-Forwarding (CBF), is developed that considers the interactions between communities as an additional factor in message forwarding and is able to exploit intermediate connections between clusters to route messages with more balanced node participation and higher levels of reliability and efficiency.

Hybrid Community-Based Forwarding: A complete energy efficient algorithm for pocket switched networks
TL;DR: The semantics of CBF is extended with the Hybrid CBF algorithm (HCBF) by optimizing forwarding inside communities by considering the social diversity (measured by Unique Interactions) and the message delivery latency is substantially improved over the other algorithms studied.

Limits of Predictability in Human Mobility

TL;DR: Analysis of the trajectories of people carrying cell phones reveals that human mobility patterns are highly predictable, and a remarkable lack of variability in predictability is found, which is largely independent of the distance users cover on a regular basis.

Bubble rap: social-based forwarding in delay tolerant networks
TL;DR: BUBBLE is designed and evaluated, a novel social-based forwarding algorithm that utilizes the aforementioned metrics to enhance delivery performance and empirically shows that BUBBLE can substantially improve forwarding performance compared to a number of previously proposed algorithms including the benchmarking history-based PROPHET algorithm, and social- based forwarding SimBet algorithm.
