The UPnP compliant devices can share data with each other and control others on a homenetwork. The device to device communication is carried out by different protocols at different levels indifferent ways within the UPnP stack which is defined for devices only. But there is no feature forapplications to share data with each other on a home network and they are very limited to share databetween the devices with similar operating systems. There is no common standard for inter-applicationcommunication using UPnP on a home network but with only inter-device communication. This paperdiscuss about the application perspective view of all protocols within UPnP stack in order to achievecommunication across applications residing within UPnP devices on a home network. This paper alsodiscuss about the possibility of using alternative protocols within UPnP stack as a replacement or anextension for effective communication and proposes an upgraded UPnP stack for applications.
