IMPLEMENTASI LINUX EMBEDDED SYSTEM UNTUK DLNA MENGGUNAKAN OPENWRT PADA MR3420 WIRELESS ROUTER

Abstrak – DLNA berfungsi dan bertujuan untuk memudahkan para penggunanya untuk berbagi/sharing konten antara perangkat. Teknologi ini sebenarnya telah banyak digunakan orang-orang dimana begitu banyak konten-konten yang disimpan pada komputer pribadi apakah itu foto, trek musik, atau bahkan file film. Dengan DLNA, pengguna dapat secara berkesinambungan mengalirkan/berbagi semua itu keseluruh isi rumah di perangkat lain yang telah terhubung seperti TV, printer, komputer menggunakan protokol UpnP (Universal Plug and Play). Dalam penerapan teknologi DLNA pada jaringan membutuhkan DLNA Media Server, Client dan Data Storage yang menyimpan file untuk diputar dalam jaringan. Dalam penelitian ini, DLNA Media Server menggunakan wireless router TP-Link MR3420 yang sudah terinstall firmware OpenWRT dan penyimpanan menggunakan Hardisk External 320GB dengan multi sistem operasi sebagai DLNA Media Client. Setelah melakukan beberapa pengujian termasuk compatibility, performa dengan parameter kecepatan read dan write pada server, power usage, network usage and total costs. Biaya yang dikeluarkan sekitar IDR 600.000 dengan daya yang dibutuhkan 7.65 watts, dan DLNA media server ini compatible dengan semua media client, tapi performanya kurang baik apabila digunakan oleh semua client secara bersamaan dan terus menerus

Extending UPnP for Application Interoperability in a Home Network

The Universal Plug and Play (UPnP) technology offers pervasive communication across heterogeneous devices in a home or small office network. The UPnP specifications are available for devices only to be interoperable together in a home or small office network. This paper proposes an extension of the UPnP technology for application interoperability in a home or small office network. This paper provides an UPnP Application Architecture as an extension to the existing UPnP Device Architecture. This extension enhances the feature of UPnP from device interoperability to application interoperability which enables the applications to discover, control and share data with each other in a home or small office network despite of their device type and operating system. In addition to the UPnP Application Architecture, the UPnP Application Template and UPnP Application Service Template are defined towards the development of UPnP-enabled applications that run on heterogeneous devices in a home or small office network.

Using Portable-Profile to Support Context-Aware Services in the UPnP Networks

The Universal Plug and Play (UPnP) network provides features for using digital devices easily without configuration. But, there are some issues such as cross network segment and security in the UPnP networks. To solve the problem, many works use an additional proxy server and a recommendation system to provide suitable services. However, the approach requires additional resources and cost and it is difficult to deploy in the digital home. In this work, we propose a new concept which the profile was portable and within user’s personal digital device. The digital device can use the profile and information such as identification, time, location, etc. to find suitable devices and simplify the operation for resource access and increase privacy. Finally, we implement the portable-profile on android phone to achieve the concept.
