TLDR
It is observed that adding small amount of infrastructure is vastly superior to even a large number of mobile nodes capable of routing to one another, obviating the need for mobile-to-mobile disruption tolerant routing schemes.Abstract:
Networks composed of mobile nodes inherently suffer from intermittent connections and high delays Performance can be improved by adding supporting infrastructure, including base stations, meshes, and relays, but the cost-performance trade-offs of different designs is poorly understood To examine these trade-offs, we have deployed a large-scale vehicular network and three infrastructure enhancement alternatives The results of these deployments demonstrate some of the advantages of each kind of infrastructure; however, these conclusions can be applied only to other networks of similar characteristics, including size, wireless technologies, and mobility patterns Thus we complement our deployment with a demonstrably accurate analytical model of large-scale networks in the presence of infrastructureBased on our deployment and analysis, we make several fundamental observations about infrastructure-enhanced mobile networks First, if the average packet delivery delay in a vehicular deployment can be reduced by a factor of two by adding x base stations, the same reduction requires 2x mesh nodes or 5x relays Given the high cost of deploying base stations, relays or mesh nodes can be a more cost-effective enhancement Second, we observe that adding small amount of infrastructure is vastly superior to even a large number of mobile nodes capable of routing to one another, obviating the need for mobile-to-mobile disruption tolerant routing schemesread more

Delay and capacity tradeoff analysis for motioncast
TL;DR: It is proved that the fundamental delay-capacity tradeoff ratio for multicast is delay/rate ≥ O(n log k), which would guide us to design better routing schemes for multicasts.

SPRING: A Social-based Privacy-preserving Packet Forwarding Protocol for Vehicular Delay Tolerant Networks
TL;DR: Wang et al. as discussed by the authors proposed a social-based privacy-preserving packet forwarding protocol, called SPRING, for vehicular delay tolerant networks (DTNs), where RSUs deployed along the roadside can assist in packet forwarding to achieve highly reliable transmissions.

Survey on Misbehavior Detection in Cooperative Intelligent Transportation Systems
TL;DR: In this article, the authors present misbehavior detection mechanisms that can detect insider attacks based on attacker behavior and information analysis, which aligns better with highly application-tailored communication protocols foreseen for cooperative intelligent transportation systems.

Spray and wait: an efficient routing scheme for intermittently connected mobile networks
TL;DR: A new routing scheme, called Spray and Wait, that "sprays" a number of copies into the network, and then "waits" till one of these nodes meets the destination, which outperforms all existing schemes with respect to both average message delivery delay and number of transmissions per message delivered.

TL;DR: The evaluations show that MaxProp performs better than protocols that have access to an oracle that knows the schedule of meetings between peers, and performs well in a wide variety of DTN environments.

Energy-efficient computing for wildlife tracking: design tradeoffs and early experiences with ZebraNet
TL;DR: The goal is to use the least energy, storage, and other resources necessary to maintain a reliable system with a very high `data homing' success rate and it is believed that the domain-centric protocols and energy tradeoffs presented here for ZebraNet will have general applicability in other wireless and sensor applications.

Telos: enabling ultra-low power wireless research
TL;DR: Telos is the latest in a line of motes developed by UC Berkeley to enable wireless sensor network (WSN) research, a new mote design built from scratch based on experiences with previous mote generations, with three major goals to enable experimentation: minimal power consumption, easy to use, and increased software and hardware robustness.

Routing in a delay tolerant network
TL;DR: This work forms the delay-tolerant networking routing problem, where messages are to be moved end-to-end across a connectivity graph that is time-varying but whose dynamics may be known in advance, and proposes a framework for evaluating routing algorithms in such environments.
