Energy-Efficient Soft Real-Time Scheduling for Parameter Estimation in WSNs
In wireless sensor networks (WSNs), homogeneous or heterogenous sensor nodes are deployed at a certain area to monitor our curious target. The sensor nodes report their observations to the base station (BS), and the BS should implement the parameter estimation with sensors' data. Best linear unbiased estimation (BLUE) is a common estimator in the parameter estimation. Due to the end-to-end pack...
متن کاملEnergy efficient routing and scheduling for real-time data aggregation in WSNs
In this paper, we study the problem of constructing an energy efficient data aggregation tree for data gathering in wireless sensor networks. We consider a real-time scenario where the data aggregation must be performed within a specified latency constraint. The objective is to minimize the overall energy cost of the sensor nodes in the aggregation tree subject to the latency constraint. We pro...
متن کاملEnergy Aware Task Scheduling for Soft Real Time Systems using an Analytical Approach for Energy Estimation
Embedded systems have pervaded all walks of our life. With the increasing importance of mobile embedded systems and flexible applications, considerable progress in research has been made for power management. Power constraints are increasingly becoming the critical component of the design specifications of these systems. It helps in pre-determining the suitable hardware architecture for the tar...
متن کاملAn energy-efficient SDN based sleep scheduling algorithm for WSNs
Energy efficiency in Wireless Sensor Networks (WSNs) has always been a hot issue and has been studied for many years. Sleep Scheduling (SS) mechanism is an efficient method to manage energy of each node and is capable to prolong the lifetime of the entire network. In this paper a Software-defined Network (SDN) based Sleep Scheduling algorithm SDN-ECCKN is proposed to manage the energy of the ne...
متن کاملEnergy Efficient Voltage Scheduling for Real-Time Operating Systems
This paper applies the concept of real-time process scheduling to a Dynamic Voltage Scaling (DVS) microprocessor. DVS allows a microprocessor to save energy by operating at the optimal voltage for the task at hand. Efficient operation requires a new class of algorithms which we term voltage schedulers. The necessary foundation for these algorithms is presented along with the foreseen implementa...
