Mobile Communications and Networks [PDF]
IEEE Communications Magazine, 2019 One of the fascinating aspects of modern communications is how it is interwoven into every new advance in technology. In fact, it is difficult to find a new technology, renewable power generation, unmanned aerial vehicles, etc., that does not feature wireless communications in some form.

Impact of Beamforming Algorithms on the Actual RF EMF Exposure From Massive MIMO Base Stations
IEEE Access, 2023 Base stations equipped with large multi-antenna systems and associated beamforming schemes provide large capacity and coverage. Massive multiple-input-multiple-output (MIMO) with beamforming was introduced as one of the enablers of 5G system performance,

Storms in mobile networks [PDF]
Proceedings of the 10th ACM symposium on QoS and security for wireless and mobile networks, 2014 Mobile networks are vulnerable to signalling attacks and storms that are caused by traffic patterns that overload the control plane, and differ from distributed denial of service (DDoS) attacks in the Internet since they directly attack the control plane, and also reserve wireless bandwidth without actually using it.

Network-Based UE Mobility Estimation in Mobile Networks [PDF]
Proceedings of the 2015 Workshop on Wireless of the Students, by the Students, & for the Students - S3 '15, 2015 The coexistence of small cells and macro cells is a key feature of 4G and future networks. This heterogeneity, together with the increased mobility of user devices can generate a high handover frequency that could lead to unreasonably high call drop probability or poor user experience.

Mobility diversity in mobile wireless networks [PDF]
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011 We introduce the novel concept of mobility diversity for mobile sensor or communication networks as the diversity introduced by transmitting data over different topologies of the network. We show how node mobility can provide diversity by changing the topology of the network. More specifically, we consider a mobile network of a sensor node and a number
