Design a real time system for a child protection system in the house in absence of parents at home to raise an alert to parents in case of any problem. (model, algorithm and Cheddar implementation). Identify the basic tasks required.
Explain what type of system it is i.e. either HARD /SOFT OR FIRM and justify your answer.
Also mention what type of scheduling algorithm can be used and justify your answer.
Also say whether it is online or offline scheduler and justify your answer

Real Time Operating system assignment questions

1. A system contains four jobs. There are two resources X and Y. The following table shows the job parameters and their execution pattern. The execution pattern describes how each job is executed. [R;t] is read as follows: the job requires the resource R for t time units. Here, job J3 requires no resource for one time unit, the resource Y for two time units and no resource for one further time unit.

(a) Use the basic priority-inheritance protocol to schedule the system of jobs. Give the schedule and show also the current priority of the executing job at all time instants.
(b) Use the basic priority-ceiling protocol to schedule the system of jobs. Give the schedule and show also the current priority ceiling and the current priority of the executing job at all time instants.
