Integrated GSM/WiFi Backhauling over Satellite: Flexible Solution for Emergency Communications

Abstract

This paper presents the development of a compact, ruggedized satellite terminal, to be used for communications in emergency situation. The terminal provides GSM coverage in disaster area, where existing communication infrastructure is destroyed or overloaded. It uses GSM backhauling over satellite to transport GSM signalling and data traffic to the core GSM network infrastructure in the disaster-safe area. Additionally, basic data services such as HTTP web browsing and email are also provided via WiFi access. Issues related to the terminal design and the tests that have been undertaken are presented in the paper.

SDN-based traffic engineering for improved resilience in integrated satellite-terrestrial backhaul networks

“…Then, the paper also develops a Traffic Engineering (TE) application based in a centralized control for managing dynamically a steerable satellite capacity provisioned for resilience or emmergency purposes. Unlike more basic strategies based in a distributed control that might be devised for simply replacing a failed terrestrial link with satellite capacity, or just activating traffic overflowing through satellite in high demanding peak-times [13] [14], the proposed scheme pursues an optimal allocation of the available satellite and terrestrial capacity so that a overall network utility is maximized under both failure and non-failure conditions in the terrestrial links or mobile cell deployments. The proposed SDN-based TE application is assessed and compared against a traditional overflow solution under different scenarios (different number of BSs with no terrestrial link availability).…”

A traffic distribution scheme for 5G resilient backhauling using integrated satellite networks

“…For example, authors in [14] propose a scheme for service prioritization under traffic congestion based on the communication needs of first responders under different emergency scenarios. In a related work, [15] studies a service classification and management scheme with two traffic classes: streaming and background. The streaming traffic class gets higher priority and ensures that the constant data rate is available to the user and the rest of the satellite channel capacity is assigned to the background class and the available bit rate may vary.…”

An Adaptive Mobile Phone Bandwidth Allocation System for Disaster and Emergency Communications

“…In 2002, Meissner et al pointed out the difficulties of designing a system for disaster communication in The First IEEE Workshop on Disaster Recovery Networks [4]. In the same conference, Midkiff et al presented a novel system for disaster and emergency response [5]. Those presentations contained the information that there are great challenges for developing an adaptive system.…”
