DLNA protocol analysis tool for smart device interoperability test

The propagation of smart devices and the rapid expansion of wireless mobile networks have increased the need for ubiquitous device connectivity and contents access. DLNA is currently being used as the de facto standard for connectivity of consumer devices in the digital home. The guidelines provided by DLNA are intended to facilitate device and contents discovery, management, sharing and distribution. In this paper, the design and implementation of a DLNA protocol analysis tool is presented for interoperability analysis among smart devices. The tool monitors the home network and performs analysis of the underlying protocols used by DLNA. The tool can be used for diagnostics and troubleshooting, enabling the developer to test DLNA functionality of Smart device
