In order to optimize the power consumption and improve the energy efficiency, the smart grid (SG) provides reliable, efficient and secured electrical power generation and distribution. Smart grid aims to manage and control the consumer demand and provide the needed power. Thus, in smart grid architecture, the information about power supply must be known, in advance, by the operator. This information...
Wireless sensor nodes operate on battery power and found very much energy constrained. Using dynamic power management, the sensor node components are operated at a desired power level or off to save the energy consumption and shorten the system activities to save power. Suitable queue discipline in collaboration with dynamic power management takes on a significant role in improvising the energy efficiency...
In this paper, we analyze the power consumption of wireless sensor nodes with min(N,T) policy and M/G/1 queue in the presence of Nakagami-m fading. In particular, this system setting is applied to a wireless sensor node operating in a cognitive radio system as secondary user in the presence of a primary user. As such, not only the queue policy influences the power consumption but also the interference...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
