—Technological evolution of mobile user equipments (UEs), such as smartphones or laptops, goes hand-in-hand with evolution of new mobile applications. However, running compu-tationally demanding applications at the UEs is constrained by limited battery capacity and energy consumption of the UEs. Suitable solution extending the battery lifetime of the UEs is(More)
— The femtocells are very promising concept for wireless networks to significantly enhance system capacity. Nevertheless, a lot of challenges must be still addressed. The paper focuses on a power control mechanism and proposes a novel approach for dynamic adaptation of transmitting power of femtocell access points. The basic idea is to adapt the(More)
A monitoring of signal quality must be performed in wireless networks since the users are continuously moving among base or relay stations. This is done via so called scanning procedure when a mobile station measures specific channel parameters. After each scanning, the mobile station reports the results to its serving station. This paper proposes a new(More)
VoIP is one of the most emerging technologies in the area of speech communications. VoIP is widely deployed in fixed line access networks. However, user’s requirements on the mobility within communication and on the quality of the speech communications are increasing. Therefore, VoIP technology is more and more integrated into broadband wireless(More)
Small Cell Cloud (SCC) consists of Cloud-enabled Small Cells (CeSCs), which serve as radio end-points for mobile user equipments (UEs) and host computation offloaded from mobile UEs. SCC hereby brings advantages of a centralized cloud computation to the users' vicinity. The SCC architecture provides a mechanism for distribution of computation demand across(More)
