This paper presents an Unscented Kalman filter (UKF) based algorithm for estimating
available bandwidth in a space Disruption-Tolerant Network (DTN) link. In the proposed …

As the main protocol of delay/disruption-tolerant networking (DTN) technology, bundle
protocol (BP) was intended for reliable data transmission in space communication networks …

The effect of a link disruption on reliable data transmission of bundle protocol (BP) is
currently under study. In this paper, a study of the effect of link disruption on BP's reliable …

A large-scale network that supports a large number of users can have an aggregate data
rate of hundreds of Mbps at any time. High-fidelity simulation of a large-scale network might …

Space communications are characterized by link intermittent connectivity and long link
propagation delay. The use of bundle protocol (BP) in space communications has been in …

In this thesis, we study the issue of estimating end-to-end delivery delays for data
transmissions in space internets. We provide solutions that deal with the challenging nature …

In this paper, we propose an efficient method to estimate the end-to-end Available
Bandwidth (AB) of a network path. This method employs multi-rate (MR) probe packet …

In the space Disruption-Tolerant Network (DTN), high-speed relative motion between the
spacecraft-piggybacking nodes leads to rapid changes of link range, which incurs the time …

Despite the notable progress that has been achieved on long-haul radio and optical
communications, which are expected to improve the data transfer rates of future space …

Disruption-tolerant networks (DTN) are very useful in situations that links are unstable and
bandwidth is precious, ie inter satellite links. Both distance and the size of transmitted …
