Abstract Remotely piloted operations of lightweight Unmanned Air Vehicles (UAV) are limited by transmitter power consumption and are always restricted to Line-of-Sight (LOS) distance. The use of mobile cellular network data transfer services (e.g. 3G HSPA and LTE) as well as long-range terrestrial links (e.g. LoraWAN) makes it possible to significantly extend the operation range of the remotely piloted UAV. This paper describes the development of a long-range communication solution for the UAV telemetry system. The proposed solution is based on (but not restricted to) cellular data transfer service and is implemented on Raspberry Pi under Gentoo Linux control. The goal of the project is to develop a flexible system for implementing optimized redundant network solutions for the Non-LOS remote control of the UAV

Network Interfaces

Existing user-level network interfaces deliver high bandwidth, low latency performance to applications, but are typically unable to support diverse styles of communication and are unsuitable for use in multiprogrammed environments. Often this is because the network abstraction is presented at too high a level, and support for synchronisation is inflexible. In this paper we present a new primitive for in-band synchronisation: the Tripwire. Tripwires provide a flexible, efficient and scalable means for synchronisation that is orthogonal to data transfer. We describe the implementation of a non-coherent distributed shared memory network interface, with Tripwires for synchronisation. This interface provides a low-level communications model with gigabit class bandwidth and very low overhead and latency. We show how it supports a variety of communication styles, including remote procedure call, message passing and streaming.

Network Interfaces

The proliferation of wired and wireless technologies has given rise to the possibility of multi-access options for mobile, multi-homed hosts. Enabling multi-access techniques improves fault tolerance by adding redundancy to network connections. For example, if a host is enabled with two network interfaces connected to the Internet via two different Internet service providers (ISPs), the failure of one network will not stop data transmission. The host will be capable of continuing the data transfer by switching over to the other network. Furthermore, if both networks are active at the same time, but packets experience higher delay and congestion on one path, multihoming facilitates the possibility of switching over to the network path offering better performance. However, the key factor in attaining the benefits of multihoming is to ensure that the handoff or switch over from one network interface (or a network path) to the other active interface should take place with minimal interruption. Stream control transmission protocol (SCTP) provides support for multihoming by allowing a single connection between two nodes to hold several IP addresses simultaneously.

AbstractData Management of Astronomy Data is often a laborious task and it is even more challenging for the extraordinary amounts of data expected from the world’s largest radio telescope, Square Kilometre Array. There are overt issues in transferring the voluminous data and the traditional data transfer methods are fragile especially for the data transfer between two continents. To address this, a new data transfer framework is proposed and the data transfer is achieved using two steps: international and local transfers. The efficiency of different end-to-end data transfer tools used in is evaluated on different dataset sizes. Further, a comparative study of two IRIS grid data transfer methods is made to understand each methods’ advantages and disadvantages. This study can be used as a reference for the development of future SKA’s data transfer operations.

Integrated Service Network

The simultaneous multiple data transmission can improve the use of the network. Unlike existing solutions in the literature, in this chapter, the authors propose a solution to the network resource allocation problem under the selfish behavior of mobile device with multiple connections to several available network interfaces simultaneously, to resolve the conflict of interest in network. They analyze the impact of interactions between users based on two conflicting factors (i.e., throughput and monetary cost). Also, a diverse set of user service types is taken into consideration, which makes the proposed approach suitable for an integrated service network. Analytical and numerical results demonstrate the validity of the proposed approach, which show that the non-cooperative game has an equilibrium point that depends on all parameters of the system, and they show that this situation between mobile devices is much more beneficial in terms of the performance of mobiles, cost, and the data transfer rate.
