With a view to understanding the luminescence mechanism in ZnSe, a systematic study of thermally stimulated luminescence (TSL) of UV ray (3650 Å) irradiated ZnSe:Ag and ZnSe:(Ag, Gd) phosphors has been undertaken. TSL glow curves of these phosphors are recorded in the temperature range 110–340 K. The TSL parameters like trap depth, frequency factor, order of kinetics, and capture cross‐section of...
Today WSNs having different important role in different fields. Generally WSNs consist of thousands of small, cost effective, constrains on memory and processing capabilities to sense data periodically from predefined region. Wireless sensor network deployed in war like area or area in which after deployment of wireless sensor network any change is not possible. So, energy consumption is one of the...
Wireless sensor networks (WSNs) have many applications in military services, health centers, industries as well as home surveillances. In such networks energy efficiency of nodes and life time of network are main concerns. Different clustering approaches are used to efficiently optimize the energy of sensor nodes. Clustering also improves the scalability of sensor nodes. We reviewed different approaches...
Today wireless sensor Networks (WSNs) has important role in various fields. Sensor networks contain many sensor nodes for the purpose of sensing the data from the environment of a particular region. The major design issue in this area is to optimize energy efficiency of a sensor node as the power source of sensor node is limited and also it is not feasible to replace or recharge the power source of...
