Recent years have witnessed rapid development of Telehealth applications and the integration of portable devices to facilitate services such as Voice-over-IP (VoIP), Video-over-IP and distribution of other data types e.g., medical images and health sensor data. In line with Telehelath, Home Area Network (HAN) has also seen broad deployments and has...

Telehealth applications such as Video-over-IP and remote sensor monitoring are rapidly growing in utilisation and it has now expanded to the patient's homes. These Telehealth applications are, however highly delay sensitive and require high quality (and bandwidth priority) in order to provide satisfactory performances. However, at the patient's hom...

Wireless Local Area Network (WLAN) has enabled greater communication capabilities compared to LAN counterpart. However, when it comes to quality of service (QoS), WLAN has lower reliability, where it has higher latency and packet-loss, especially for real-time streaming applications such as voice over internet protocol (VoIP) and multimedia. Thus,...

In this paper, the performance VoIP is investigated for IPv4, IPv6to4 tunneling mechanism, for various VoIP codecs, namely the G.711.1, G.711.2, G.723.1, G.729.2 and G.729.3 codecs using Windows Vista and Windows 7 operating systems. Parameters studied are jitter, RTT (round trip time) and throughput. The results indicate that IPv6to4 tunneling gen...

In this paper, the performance of Video Protocols was tested on three well known IP transition mechanisms such as IPv6to4, IPv6in4 and Dual-Stack. The protocols involved in this experiment were MPEG-1, MPEG-2, and MP-4 protocol. In this experiment two tunnelling and a Dual-Stack mechanisms were configured and impact of these mechanisms on Video pac...

This paper investigates the performance of Video Protocols over IPv6 and IP transition mechanisms. It mainly focuses on the impact caused by IP transition mechanisms on video packets and compares this with pure IPv6 based networks. The video protocols selected in this experiment were MPEG-1, MPEG-2, MPEGP-4, MKV and FLV. In this experiment a Dual-S...
