GStreamer is a pipeline-based multimedia framework written in the C programming language with the type system based on Gobject. Aiming at transmitting streaming media in simplex wireless channel with stochastic time slot, our paper propose a new framework based on Gstreamer to achieve real-time video collection in multi-resolution and adjustable frame rate. The video is then encoded in X264 which...
In this paper, new fountain codes named LT-LR-DRS (Luby Transfer with Loss Rate and Decreasing Ripple Size) codes are proposed for wireless relay communications. The transmission is divided into two phases: at first phase, all original symbols are transmitted and some original symbols are lost during transmission; encoded symbols generated by LT-LR-DRS codes are transmitted at second phase to recover...
In extremely low-duty-cycle wireless sensor networks, a sender has to wait for a certain period of time to forward a packet until its receiver becomes active, which will result in longer end-to-end delay than ever. Many works have been done to improve delivery ratio but lack of the consideration on energy efficient delivery delay. In addition, unreliable links is another challenge in wireless sensor...
