The Importance of Task Scheduling in IoT

One of the most important aspects in an RTOS is task scheduling since it defines the sequence in which many operations run on the CPU at the appropriate instant. Each process or task in the context of real-time applications has a particular function, such reading sensor data, handling images, or sending messages to other devices. 
 
Scheduling takes great significance in applications using the Internet of Things (IoT) as many devices connect with one other and engage their surroundings using sensors and actuators. Usually having strict timing demands, IoT applications need dependability and rather quick reactions. An IoT greenhouse system, for instance, has to continuously monitor temperature and moisture in real time while also controlling ventilation or irrigation on time to keep ideal conditions. 
 
Task scheduling in an RTOS is geared toward two primary objectives: 
 1. Feasibility: Every job needs to be finished by its deadline; nothing is left out. 
 2. Optimality: Optimize characteristics including CPU use, power consumption, and reaction time such that the system performs effectively. 
 
Attaining both objectives is difficult since there are usually several duties with varying priorities, execution periods, due dates, and dependencies. In addition, task scheduling helps considerably with: 
 - Making sure projects fulfill Quality of Service (QoS) specifications including low latency, great throughput, reliability, and energy efficiency. 
 - Improving the use of CPU, memory, bandwidth, and power among other resources. 
 - Managing the workload on multicore systems. 
 - Adjusting to shifting environmental circumstances including fluctuating workloads, network conditions, et cetera.
