     16 * Overview of current functions  [[BR]]
     17  * [http://groups.geni.net/geni/attachment/wiki/GEC15Agenda/WiMAXUpdate/mse-banerjee.pdf  slides]  [[BR]]
     18  * A data measurement framework with APIs, that the clients and the measurement server expose  [[BR]]
     19  * Clients (e.g., on an Android device) measure network performance, and then report measurements to the server  [[BR]]
     20  * Measurement include latency, loss, throughput, TCP or UDP  [[BR]]
     21  * Provides feedback to network selection  [[BR]]
     22  * [http://wiscape.wings.cs.wisc.edu/new_wiscape/index.php  link to WiScape]  [[BR]]
     23
     24What are next steps?   [[BR]]
     25 * Work with handover project, to see if WiScape measurement framework can be part of a GENI mobility/handover/multi-homing solution  [[BR]]

     31 * Projects requiring handover include:  Clemson, Wayne State, Wisconsin and UCLA.    [[BR]]
     32 * Projects that can contribute handover technology include:  Rutgers WINLAB and Wisconsin.  [[BR]]
     33 * Also, commercial handover technology available from Airspan.  (Gregg Tome (Airspan))  [[BR]]

     36
     37 * Layer 2 handoff
     38  * Minimal:  Mobile node breaks its connection with current WiMAX BS and then establishes connection with the new WiMAX BS  [[BR]]
     39  * Better:  Mobile node needs two interfaces, in the simplest form, one interface always connects to BS1 while the other connects to BS2  [[BR]]
     40  * Need: suggested configurations, estimates of required software and level of effort  [[BR]]
     41
     42 * Layer 3 handoff
     43  * Minimal:  Controller node re-routes through new BS after IP address re-write, BUT does not allow initiation of incoming connection
     44  [[BR]]
     45  * Better:  Use open source mobile IP s/w (Transparent Mobile IP [http://sourceforge.net/projects/tmip/ link], and OpenFlow s/w in mobile node to de-encapsulate IP packets  [[BR]]
     46  * Need: suggested configurations, estimates of required software and level of effort  [[BR]]
     47
     48 * Suggested steps:    [[BR]]
     49  1) Yellow mobile nodeode with two interfaces, doing handover between two BS on the same subnet [[BR]]
     50  2) Transparent MobileIP working to implement a baseline Layer 3 handover scheme [[BR]]
     51  3) Support new Layer 3 solutions like Mobility First? [[BR]]
     52  4) Demonstrate heterogeneous network handovers [[BR]]
     53
     54What are next steps?   [[BR]]
     55 * Better define proposed configurations 1) and 2) (due 11/15/12)  [[BR]]
     56 * Review with other interested projects  [[BR]]
     57 * Understand proposed Multiple Base-Station Mgmt Srvc and  Data-Path GW Srvc, and how they could be used in the implementation  [[BR]]
     58 * Understand how Yellow Nodes could be used in the implementation  [[BR]]
     59 * Understand how Android handsets could be used in the implementation  [[BR]]
     60 * Consider potential uses of WiScape Measurement Framework  [[BR]]
     61 * With other projects, define a workplan  (due 12/15/12)  [[BR]]
