Mirai

Yesterday, 13th April I had a meeting with my supervisor. I showed what I had done for the last 1 month. We disscused some problem regarding the simulation using the HS-DSCH transport channel.

So at the end of the meeting, he introduced me a new discrete network simulator called mirai developed by Wireless Applications Group on the Next Generation Mobile Network Project, National Institute of Information and Communications Technology (NICT).

So my simulation DiffServ in EURANE core network using HS-DSCH is still pending until I find a solution.

what to do...

Things that I have achieved so far:-
-----------------------------------
1. A simple simulation on DCH channel with DiffServ in the core network. Two UDP sources with constant bit rate traffic are to simulate the VoIP data packets. Throughput at the ssgn which is configure as an edge router are measured in term of Mbps.

Things that I did:-
-------------------
1. Read the Seacorn deliverable D3.2v2.
2. Read thesis on QoS provisioning.
3. Read TS 23.207


Things to do:-
--------------
1.Read 3gpp technical document on End-to-end QoS and HS-DSCH.
2.Find out why simulation on HS-DSCH channel with DiffServ in the core network stop abruptly. It should not have any problem because Diffserv is working on the network layer. Mac-Hs is the important mechanism for HS-DSCH which is on the data link layer.
3. Find some script to analyse the trace file for end-to-end delay and jitter.

Things to do as on 20th March
-----------------------------
1.Read and understand
2.Build some simple simulation scenarios.
Check with 3gpp standard for QoS
