Proxy Mobile IPv6 (PMIPv6) is a network based IP mobility management protocol. PMIPv6 make sure that the IP address of the mobile node remains the same as long as the mobile node roams with in the PMIPv6 domain. A mobile node roams with in a PMIPv6 domain. PMIPv6 protocol doesn’t provide the mobility support once the mobile node moves from one PMIPv6 domain to another PMIPv6 domain. This paper proposes a Software Defined Networking (SDN) based PMIPv6 scheme which provides the mobility support for inter PMIPv6 domain movement of mobile node. In the proposed architecture each PMIPv6 domain has a SDN controller and SDN controllers from different domains communicate with each other to share the mobility information.
