Cognitive Radios (CRs) address the problems of spectrum scarcity and under-utilization of the spectrum. However, realizing a CR network is neither easy nor straightforward. The link layer in CR Ad hoc Networks is responsible for allocating suitable channels, out of the currently available channels. It is also responsible for setting up communication between(More)
Providing detailed appliance level energy consumption information may lead consumers to understand their usage behavior and encourage them to optimize the energy usage. Non-intrusive load monitoring (NILM) or energy disaggregation aims to estimate appliance level energy consumption from the aggregate consumption data of households. NILM algorithms, proposed(More)
AIM To study expression of p53 protein and ki-67 antigen in normal, non-dysplastic, dysplastic, premalignant and malignant lesions of the oral mucosa. MATERIALS AND METHODS The standard immunohistochemical method along with MIB-1 and DO-7; DAKO antibodies was used to study the expression of p53 and ki-67 in paraffin-embedded tissue specimens. RESULTS(More)
—We propose demonstrating an IEEE 802.11ah wireless local area network (WLAN) prototype that is configured as a self-contained machine-2-machine (M2M) wireless sensor system. Because the IEEE 802.11ah protocol standardization is under way, no commercial-off-the-shelf (COTS) IEEE 802.11ah Wi-Fi product is available yet. However, the proposed prototype has(More)
Context awareness is an important aspect in many ICT applications. For example, in an intelligent home network, location of the user enables session transfer, lighting, and temperature control, et cetera. In fact, in a body area sensor network (BASN), location estimation of a user helps in realizing realtime monitoring of the person (especially those who(More)
With the rapid development in wireless devices, applications and networks, radio frequencies have become scarce resources. Therefore, it is critical to make efficient use of the radio frequencies. A promising way to solve this problem is the use of cognitive radio (CR). In CR, radio frequencies are allocated to licensed users, also called primary users(More)
