UROP: A Simple, Near-Optimal Scheduling Policy for Energy Harvesting Sensors
This paper considers a single-hop wireless network where a central node (or fusion center, FC) collects data from a set of m energy harvesting (EH) nodes (e.g. nodes of a wireless sensor network). In each time slot, k of m nodes can be scheduled by the FC for transmission over k orthogonal channels. FC has no knowledge about EH processes and current battery states of nodes; however, it knows ou...
متن کاملOptimal Offline Broadcast Scheduling with an Energy Harvesting Transmitter
We consider an energy harvesting transmitter broadcasting data to two receivers. Energy and data arrivals are assumed to occur at arbitrary but known instants. The goal is to minimize the total transmission time of the packets arriving within a certain time window, using the energy that becomes available during this time. An achievable rate region with structural properties satisfied by the two...
متن کاملSensors for Energy Harvesting System
A considerable attention has been given to the energy harvesting system, as the energy obtained from this system is used for powering up small electronic devices instead of using batteries. Battery manufactures make batteries of required size with long life of usage. However, it is difficult to replace such batteries once its life is expired. This difficulty can be partially overcome by using t...
متن کاملDelay Optimal Scheduling for Energy Harvesting Based Communications
Energy harvesting has attached considerably attention for its wide application in wireless green communications. Equipped with a rechargeable battery, a source node can harvest energy from ambient environments and rely on this free and regenerative energy supply to transmit packets. Due to the uncertainty of available energy from harvesting, however, it could induce intolerably large latency an...
متن کاملOptimal Packet Scheduling Using Energy Harvesting For Wireless Sensor Network
Real time and non-real-time data packets are the two types of scheduling packets which is used at sensor nodes with resource constraints in WSN of importance to reduce sensors energy and end-to-end delays. Existing First Come First Served, starvation of high priority real-time data packets due to the transmission of a large data packet in nonpreemptive priority scheduling, starvation of nonreal...
