The project nameas :
"IMPROVING THE STABILITY of REAL TIME COMMUNICATION MEDIA for MANET"
The project aims:
This project aim to use "ad hoc mobile network" (MANET) for real time network control systems, with the maintain of thenetwork control systems stability.
There are many challenges in using manet , as the time delay that happen when packet transmission over the network and packet losses , also because of the jitter between packets transmission ,
The achievement ofgettingthe bestperformance:byreducingsome of the reasonsthat may affect theperformance ofthe system,as we said this reasonsis the presence ofatimedelaywhentheconnection between theController andthe plantusing manet, because oftimes overthetransferpackage, jitterandincrease(packet drop rate) so it mustanalyzingthe performance ofthe systemthrough the work ofa mathematical model.
1.We must design a control system with plant and controller using matlab.
2. Design a manet network using opnet programming.
3. Co-simulation between opnet and matlab using mx-interface, also the data must be synchronous as shown in this paper number [2] below.
4. After showing the result there must be a delay appear in control system responses and this will effect on the performance of the system.
5.Then it must be enhance some of the manet routing protocols to achieve a stable network control system responses, so we chose a GRP protocol in this work to be develop to achieve the stability with a system that have a small fraction of the time delay.
