Ping during Handover

[INDUKURI MANI VARMA 21911012]

Sir,

I created a simple topology as shown in image. I want to communicate messages between station and AP and then to Ryu SDN controller. For this, I need to establish socket connection between station and APs and between station and APs. I am failing to do so. I somehow want to share data from station-AP-Ryu. I tried in the following cases

Case 1 : Aps as OVSKernelAP.

Controller pushes flow rules when sta1 pings sta2. Why can I not ping AP1’s IP from sta1 in AP1 domain ? In mininet-wifi console, sta1 pings ap1 but not the IP address of ap1.

Case 2 : Aps as UserAP.

When APs are in userAP class and in root namespace, I can ping AP1 and AP2 in AP1 domain but not when station moves to AP2 domain. I don't understand why I am not able to ping AP2. How do I achieve this scenario ?

Is there a way stations should ping APs after association and also send socket messages to controller through AP. Please help me if I am wrong somewhere. Thank you.

This is the topology. In this topology, please sta2 mentioned in description is in AP2 region.
