Network coded cooperation in delay tolerant networks

2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2016
Implementation of network coding (NC) is expanding to a diverse set of networks due to the flexible design provided through its use, enabling a trade-off between robustness and spectral efficiency. In this paper, we investigate the application of NC in delay tolerant networks (DTN) through the use of software defined radio (SDR) nodes.

DANCER: The routing algorithm in delay tolerant networks based on dynamic and polymorphic combination of dimensions and energy consideration

International Journal of Distributed Sensor Networks, 2017
Be differ from traditional networks, the nodes in delay tolerant networks are connected intermittently and they are mobile continuously, which result in high transmission delay and low delivery ratio. In addition, the energy of the mobile node is finite.

On the Potential of Enhancing Delay-Tolerant Routing Protocols via Age of Information

Future Internet, 2022
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 harsh ...

Live-streaming in delay tolerant networks [PDF]

Proceedings of the 6th ACM workshop on Challenged networks, 2011
Streaming of audiovisual media contents such as video or music using mobile devices and wireless networks leads to new challenges because these network connections are typically not very reliable. In this demo, we show streaming of live video using a Delay Tolerant Network (DTN) approach.

Mobility Similarity-Based Routing in Buffer-Limited Delay Tolerant Networks

International Journal of Distributed Sensor Networks, 2015
In delay tolerant networks (DTNs), multiple-copy routing is often adopted to improve the probability of successful message delivery but causes more traffic loads. The excessive increase in multiple messages copies often exhausts the network resources and

Dynamic RACH Partition for Massive Access of Differentiated M2M Services

Sensors, 2016
In machine-to-machine (M2M) networks, a key challenge is to overcome the overload problem caused by random access requests from massive machine-type communication (MTC) devices.

Practical Routing in Delay-Tolerant Networks [PDF]

IEEE Transactions on Mobile Computing, 2007
Delay-tolerant networks (DTNs) have the potential to interconnect devices in regions that current networking technology cannot reach. To realize the DTN vision, routes must be found over multiple unreliable, intermittently-connected hops. In this paper we present a practical routing protocol that uses only observed information about the network.

A Routing Protocol for Delay-tolerant Networks

MATEC Web of Conferences, 2015
Epidemic algorithm improves the delivery rate by generating a large number of copies of the message. It is easy to implement and obtain high delivery rate. However, DTN network is usually memory-and-bandwidth-limited. The copy and distribution of message

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
