The application of mobile technologies in communication systems could be tracked back into the 1980s. The emerging of cognitive radio targeted on the revolutionary spectrum access paradigm has sparked a radical change in wireless mobile system design, development, and performance analysis. Since then, the state-of-the-art of wireless communications has been significantly advanced, from substantial improvement on spectrum usage, smart adaptation and coexistence in radio and network environments, fundamental enhancement on performance and capacity, to a considerable reduction of complexity in mobile network management.

1 Crypto Model of Real-Time Audio Streaming Across Paired Mobile Devices
In this research paper, authors E. O. Ibam, O. K. Boyinbode, I. O. Ayelabowo from Federal University of Technology Akure, Nigeria, aim at developing a real-time audio encryption application between two or more handheld mobile devices, the communication between devices is made secure by encrypting the audio sent in real-time using Advanced Encryption Standard (AES) 256-bit encryption key while channelling message through a cloud-hosted database (Firebase) that works as a real-time database and performs implicit AES encryption and decryption on its data. Geocoder from the Google Map API library services is used to track the location of the audio sender. Crypto Model of Real-Time Audio Streaming Across Paired Mobile Devices appeared in the issue 17 of EAI Endorsed Transactions on Mobile Communications and Applications.
2 Performance Evaluation of Multi-protocol Label Switching-Traffic Engineering Schemes
In this research paper, authors Iflah Aijaz and Sheikh Mohammad Idrees, describe that the priorities of traffic engineering are one of two groups. The first is traffic-related performance targets like reducing packet loss, reducing end-to-end delay, etc. Additionally, there are efficiency-related goals, such as a balance of traffic allocation through usable bandwidth resources. The performance goals associated with traffic are set to reach the contracted level of services and offer customers competitive services. All communication through this link is disrupted if a network connection is not established. Techniques to improve the effects of hardware failure, networks have been used to replenish the traffic from the failed link to other working connections. The main theme of this paper is to develop methods and tools that study and evaluate Multiprotocol Label Switching (MPLS) and MPLS-Traffic Engineering schemes. Performance Evaluation of Multi-protocol Label Switching-Traffic Engineering Schemes appears in issue 19 of EAI Endorsed Transactions on Mobile Communications and Applications.
3 Toward 5G High Utilizations: A survey on OFDMA-based Resource Allocation Techniques in Next-Generation Broadband Wireless Access Networks
In this article, authors Ibrahim Al-Surmi, Ali Mohammed Mansoor, and Aqeel Abdullah Ahmed, cover the topic of LTE network technologies. LTE is marketed as 4G standard for wireless communication services. LTE network technologies provide high speed triple play services like data, voice, and video with QoS provision. The resource allocation techniques’ primary concerns are the QoS support that aims to satisfy the diverse service requirements as well as to guarantee the required data rates from the available resources. In this context, different network architecture for broadband wireless data network like LTE made OFDMA a practical access technology for wireless multimedia services. Therefore, this survey investigates the techniques that aim to support QoS for real-time and non-real-time services in OFDMA-based packet scheduling and adaptive multiuser frequency-time domain resource allocation. Moreover, this survey addressed the different aspects of resource allocation algorithms design to be contributed to the emerging 5G next-generation networks. Toward 5G High Utilizations: A survey on OFDMA-based Resource Allocation Techniques in Next-Generation Broadband Wireless Access Networks appears in issue 18 of EAI Endorsed Transactions on Mobile Communications and Applications.
4 The Review of Mobile Applications and Wireless Technologies in Sustaining K-12 Schools during COVID-19
Mobile-learning (M-Learning) is no longer a futuristic concept in E-learning. The disruptions induced by the mandatory social distancing norms amidst the COVID-19 pandemic has brought it to the centre stage as it facilitates seamless delivery of education to mobile-users on the go. The ever increasing penetration of low-cost smartphones and remarkable advancement in wireless communication technologies has made M-learning ubiquitous and affordable. Authors of this paper, Karuna Samuel Finch, Srikant Manas Kala and Vanlin Sathya, highlight the roles that mass-adoption of mobile phone devices have played in sustaining K-12 schools. The Review of Mobile Applications and Wireless Technologies in Sustaining K-12 Schools during COVID-19 was published in issue 18 of EAI Endorsed Transactions on Mobile Communications and Applications.
5 Monitoring Patients in Ambulatory Palliative Care: a Design for an Observational Study
Authors of this study, Vanessa C. Klaas, Alberto Calatroni, Matea Pavic, Matthias Guckenberger, Gudrun Theile and Gerhard Tröster, present the setup of an observational study that aims to examine the application of wearables in ambulatory palliative care to monitor the patients’ health status – especially during the transition phase from hospital to home since this phase is critical and often patients are re-hospitalised. Following an user-centred design approach, we performed interviews with patients recruited at the Clinic of Radiation Oncology of the University Hospital Zurich, Switzerland. Monitoring Patients in Ambulatory Palliative Care: a Design for an Observational Stud was published in issue 17 of EAI Endorsed Transactions on Mobile Communications and Applications.
