 Problem Statement 

You are going to design a system which monitors vital parameters of patients and transmits it over a wireless  network. The system is dynamic and has the following constraints: 

? Total number of packets which can be transmitted at a time 

? Time duration for transmission 

? Transmission delays in the network 

? Being connected to an Access Point 

 

In a system, there are patients with different kinds of cardiac diseases, which are measured or detected  through patient’s ECG devices or ECG monitors. The devices help to detect and measure low-high blood  pressure, temperature, arrhythmia, etc. The patient model is categorized with different patients based on  what diseases they have (e.g BP Patient, Patient with high temperature, Arrhythmic, etc.). This model is  called as ‘Patient’. 

Another model is Network/Channel over which these data/parameters are passed as packets. These packets  are transmitted over this network only if the network is free. If the network channel is occupied then, the  packet has to wait. The packet keeps on checking the availability of the network channel to pass through it.  So every time the Patient packet sends a request to transmit to the network channel, the n/w channel will  reply as ‘Accept’ if the network is free. This model is called as ‘GATE’. 

The third model is‘Controller’ which controls the ‘Gate’. In the Controller, priority number is assigned to  each of the patients. Assuming there are multiple patients whose data packets need to be transmitted over  the channel. Priority Number is assigned to each patient. The patient having higher priority number get  ‘Accept’ first than the lower priority patient. If two patients having similar priorities, then the chance is  given as an FCFS basis. 

? The above three models shall be represented in three templates in the UPPAAL editor (Patient,  Gate and Controller). You can program your logic with respect to the models in ‘Project  Declaration’ or ‘System Declaration’ inside UPPAAL editor. 

 

Part 1 

Inputs: 

? Max patients = N 

? Max type of sensors = K 

? Time for each packet transmission = t 

? Number of Access points (AP)= A; Queue for each AP; AP will transmit packets at a rate R[ap1, ap2, apA] per second. 

? Each sensor k[i] will generate m[i] packets 

Generate randomly n patients [0,N] during a time period T (Hours), each with a random set of sensors  corresponding to a binary matrix [0,0… K]. Each sensor generated packet will be put on a queue corresponding  to an AP using Roundrobin scheme. 

Run for multiple times and obtain the following 

1. Total delay in transmission of packets 

2. Total delay in transmission for all packets for an individual
