Dear researchers and developers,
I have simulated a BAN network with 10 nodes using Castalia 3.2, I have used the MAC and radio module parameters to evaluate the performance of the studied network.
Now, I would like to know what are the acceptable packet loss rate and delay for medical applications in a BAN knowing that in some simulation cases we are forced to exceed the allowed SAR (Specific Absorption Rate) (1.6 w/kg) by increasing the transmission power to minimize packet loss rate. Our goal is to change the transmission powers to find the acceptable packet loss rate and delay for medical applications.
Can you help me know how to simulate working two performance evaluation metrics with Castalia? or Are there any articles in the literature that can inspire us?
Best Regards
Dear Amiri Marwen
The acceptable delay in BAN is between 125 to 250 mill second.
This thesis will help you:

Best wishes,
Thank you for your reply Mr Mohammed Ameen A. Abdo
ok I will see the thesis, there is other papers that describe my problem ? because I want to vary the transmission power and control the SAR value to have an acceptable delay and PLR.
Dear Amiri Marwen ,
I will a conceptual answer which may help you to find out the suitable communication performance parameters of your network.
You want to define the the so called quality of service which are:
The required maximum bit rate,
The bit error rate rather than the packet loss rate.
And the delay of the signal from the source and destination node.
The maximum bit rate depends on the signal to be transmitted.
The bit error rate for voice like signal must be better than 10^-4
The bit error rate for critical data applications must be better that 10^-6
The delay of packets depends on the application whether it is on line or off line communication.
So, you have to search for the quality of service for medical signals.
This review article may help you to get out the required performance parameters of your network.

If you want to improve the transmission parameters you can increase the signal bandwidth. Increasing the signal bandwidth will enable you to decrease your transmit power to the safe operating values. You can use the spread spectrum for this application or you can use forward error correction.
