Voice Streaming over a Sensor Network
نویسندگان
چکیده
Sensor networks have become a major area of research for low power wireless embedded development. This paper takes the approach of proposing and implementing a system which goes against traditional low-duty sensor network applications. We propose and implement a prototype for the end-to-end streaming of voice communication over a multi-hop sensor network.

متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملFireFly: A Cross-Layer Platform for Real-Time Sensor Networks
We propose a cross-layer approach with tightly-coupled time synchronization for real-time support and predictable lifetime in battery-operated sensor networks. Our design spans a sensor hardware platform with hardware-based global time synchronization, a TDMA link layer protocol with collision-free multi-hop support and node scheduling algorithms for maximum concurrency and streaming. Our dual-...
متن کاملTimed PR-SCTP for Fast Voice/Video over IP in Wired/Wireless Environments
IIn this paper, we have successfully implemented a seamless handoff between heterogeneous networks to achieve a fast voice/video over IP (V oIP ) with Partially Reliable Stream Control Transport Protocol (PR-SCTP) instead of TCP or UDP. In order to improve real-time video/voice streaming over IP, the conventional framework IHU has been remodeled as a new framework called SCTP-IHU that can simul...
متن کاملA Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding
Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...
