In our previous work [6], we proposed a cluster based two-phase PPIR protocol to repair the lost packets among end users during the 3G Base Station (BS) broadcast. The PPIR protocol achieves better performance compared with others since cluster heads have the full knowledge of each cluster and collect the data packets efficiently by exchanging control information with cluster members during the first...
Recent researches of network structure are moving to high-level networks because there are already many research results of low-level network. Especially, current network services has been changed to the multimedia service using multicast routing such as IPTV (Internet Protocol Television) service. Then the same as the existing multicast services to multiple users at once placed to transmit the purpose...
SIP (session initial protocol) is a signaling protocol widely used in IP-based multimedia communication. Recently, P2PSIP reduces the deployment and maintenance cost, as well as improves the robustness and scalability of SIP-based system. SIP, P2PSIP network will coexist in the forthcoming future. This paper focuses on the P2PSIPand its relationship with SIP. We design and implement a P2PSIP adaptor,...
The provision of innovating multimedia services is a high priority for service providers. Due to the the high traffic volume characteristics of multimedia content, decentralised services are a desired solution for multimedia scenarios. Based on the ongoing work of the IETF P2PSIP WG this paper defines a simple way to interconnect different domains using on peer-to-peer technology. The objective is...
Multimedia Broadcast/Multicast Service (MBMS) allows a common broadcast channel to be shared by users interested in identical content. We explore the problem of enhancing MBMS resilience by repairing packets lost during broadcast. Since MBMS broadcast consumes expensive 3G resources, we leverage the ubiquity of multi-homed mobile devices i.e., devices having both cellular and IEEE 802.11 wireless...
