Term Big spectrum data refers to big data in the wireless domain, containing information about radio environment awareness. Radio environment awareness is essential for the process of regulating the use of radio frequencies, for social benefit. It is an important step towards the efficient and effective utilization of the spectrum, called spectrum management. Near real time big spectrum data analysis...
Multimedia applications in the wireless domain require not only contention-based communication, but also reservation based one. The IEEE 802.15.4 standard is widely used for Wireless Sensor Networks (WSNs), and is a standard for low rate, low power and low cost WPANs (Wireless Personal Area Networks). Moreover, it supports the allocation of Guaranteed Time Slot (GTS) to the devices in Contention free...
Cognitive Radios (CRs) address spectrum scarcity and under-utilization of the spectrum. However, realizing a CR network is neither easy nor straight-forward. In particular the link layer should facilitate setting up of communication between nodes enabling sharing of channels, while maximizing the spectrum utilization. We address the problem of allocation of channels to CR nodes. For time-slotted model,...
