		+	* Working with Saleh on the problem formulation with patching, specifically to maximize the service ratio. The dependency introduced by patching (need to accommodate patching segments for the required users if they receive multicast segments with some missing segments) causing some difficulties in the algorithm.
		+	* Waiting for OPNET license to start implementation of the current phase.

		+	* Prepared the elaborated documentation on resource allocation problem in heterogeneous networks, I previously worked on covering as much as I can.
		+	* Contacted OPNET support to get price quotation for maintenance. Also asked them whether they have added the support for a single user to expand multiple sub-bands with different MCS modes, but have not received any reply yet.
		+	* Discussed some ideas with Saleh about how to direct our hybrid-streaming work to maximize number of users served as the primary goal.
		+	* Quickly explored NS-3 mainly about the support to allow a user to expand multiple sub-bands with different MCS modes while allocating resources for that user. Unfortunately, according to user forum reply, NS-3 does not support this feature.
		+	* Tried to figure out two closest related work for evaluation purpose for resource allocation problem in heterogeneous network.
		+	* Tried to find out some performance metrics along with some experimental consideration for resource allocation problem in heterogeneous network.
		+	* The details report can be found [https://cs-nsl-svn.cs.surrey.sfu.ca/cssvn/nsl-members/mrahman/thesis/ThesisProposal(Combined)/extended_documentation.pdf here].

 * But it is implementable, although not trivial. Their response on the implementation issue is:"Unfortunately, changing this behavior in the model is not trivial because :
-a) The 3GPP specifications their selves (at least the version used for the model) do not provide any guidance or defined procedures on how to achieve that.

-b) As I mentioned, a lot of the estimation and internal settings of the MBSFN model occur when the simulation is being initialized at time zero. Trying to make this on demand basis over the simulation is not trivial. Many aspects of the network are involved including capacity, for example you will need to define and implement the behavior to handle the capacity for GBR unicast bearers, this is because changing the MBMS area will change how much resources are available for GBR (this is just one among many aspects that need to be handled).

 * We are planning to add a new state containing the initialization part associated with MBSFN Area. We will bring this portion of code from attribute_definer which is responsible for the initialization based on attributes defined in the simulation. When we need to change the MBSFN Area based on our algorithm, we will update the MBSFN Area and will do the re-initialization by a state transition to our newly created state. Now, we are looking into the code for this approach.
 * Conducted a literature review on "video on-demand mobile prefetch" and tried to accumulate ideas to incorporate prefetching into the hybrid streaming approach.
