Spring 2013
- Courses:
- None
January 23
- Read some papers to construct the literature review. The report can be found here.
- Working on the implementation. Previously, I modified a function that is responsible for channel-dependent user assignment. I also need to design user queue selection algorithm and may be downlink frame generator as well to modify the creation of downlink control information (DCI)s.
January 17
- Worked on the implementation of heuristic algorithm for resource allocation without adaptive power.
- Updated system architecture and other things. Details report is available here.
Fall 2012 (RA)
- Courses:

January 3
- Helped Saleh in his work with OPNET to record the MCS for all users in the system in scheduled time.
- Wrote the first draft for system architecture for my work and reported to Abdul Hasib.
- Looked into OPNET code and figured out how to obtain sub-band specific CQI along with wideband CQI.
- Explored how Channel Dependent Scheduling is done in LTE and now specifically looking into OPNET code how they handle this.
December 15
- Completed the course project.
- Now will focus back on my thesis.
December 8
- Prepared the Thesis plan.
- Designed the heuristic algorithm for OFDMA radio resource allocation.
- Worked on the course project.
November 24
- Helped Abdul Hasib in generating mobility results for the proposed algorithm as to complete comments.
- Created the EPS format figures.
- Measured the runtime for both the proposed greedy algorithm and the optimal solution. For measuring the runtime for the greedy algorithm, reimplemented it in Matlab to keep the measuring environment uniform for both algorithms.
- Worked with Saleh to help him to get started with OPNET for his implimentation with explanation of how can he implement his work.
- Worked on the design of heuristic algorithm for our work and reported to Adbul Hasib.
November 11
- Did group seminar presentation.
- Working on the Course project. It is taking enough time.
- Looking into the OPNET scheduling for LTE.
October 28
- Did a survey on empirical data search on utility values for different application data rate. There are two ways to obtain utility values for different application data rates: survey based data and utility functions based data. I found all the papers I went through using utility function based data.
- Working on Internet Architecture and Protocols project: Smartphone Network Energy Management- attempt to save mobile power by controlling wireless transmission.
- Looked into the computation of wideband CQI. It turns out that OPNET computes wideband CQI based on the entire channel condition.
- There are two ways to allocate power to sub-bands: 1) same power to all-bands which is a bit easier from developer's perspective and 2) different power to different sub-bands. It turns out that OPNET uses the first approach.
- Prepared for group seminar presentation.
October 13
- Could not work for a week due to severe back pain and fever.

August 18
- Implemented the proposed algorithm in OPNET for single cell.

August 4
- Figured out and solved the problem how we can allocate MBMS subframes in consecutive frames in Common Subframe Allocation (CSA) period.
- Figured out where MBMS group membership for UE is registered and changed it with some test data.
- Figured out how to obtain wideband MCS for a particular UE with Link Adaptation in MBMS. In MBMS, MCS obtained by Link Adaptation is not used for MBMS transmission, rather it uses MCS from Bearer Configuration in MBMS.
- Figured out IP sub-module that handles multicast group JOIN and LEAVE requests and can now join/leave multicast group dynamically from code with some restrictions.
- Running various OPNET simulations and exploring code related to simulations.
July 22
- Did various OPNET simulations to identify different aspects of MBMS in OPNET.

- Read the power efficient Multicast-Unicast video-on-demand streaming algorithm over LTE Networks proposal and some other MBMS documents.
July 9
- Experimented with the OPNET Lab to control the range of eNodeBs with FTP and Voice applications.
- Still exploring the OPNET code specifically the resource allocation part. It is too large and complicated as it involves physical layer heavily.
- Wrote a parser to generate frames out of OPNET debugging information. It will help to visualize different frames.
June 24
- Explored utility curve for various applications as we have a plan to consider a mixture of different types of applications instead of a single type application with benefit of real time applications in mind.
- Still exploring the code and doing experimental modifications to learn different aspects. I found forum support for OPNET poor as no replies in the forum yet. I emailed my queries to support and they replied, "your organization's maintenance contract with OPNET has expired".
- Explored some OPNET labs from OPNETWORK 2010 and 2011 covering OPNET Modeler and LTE to gain some more details about OPNET and LTE in OPNET. Since, we don't have maintenance license, I requested one of my friends in Engineering school who's lab has OPNET maintenance license to download those labs for me.
June 10
- Looking into the coding details in OPNET.
- The initial plan is to implement the basic load balancing user association rule and compare the results with two cell search algorithms namely First suitable cell and Best suitable cell for which built in support is provided in OPNET. Then we will devote more concentration to the design of more robust algorithm and implement that.
- Getting a bit problem finding out eNodeB load and looking into more details in the code. Posted into OPNET forum with no replies and that's why digging into more details.
May 29
- Studied Mobility Management/Handover in Macrocell/femtocell LTE networks. The main challenges lie within hand-in (handover from macrocell to femtocell) which itself is another research field. It has issues like discovering neighboring femto BS, admission control and selection of appropriate femto cell for handover.
