چکیده

The use of mobile devices capable of wireless communications such as mobile phones, PDAs, and laptops in disaster recovery has been an important research topic for several years. However, while the majority of previous research has focused on voice and data communications a small number of researchers have proposed the use of multimedia content in aiding with patient diagnosis. Disaster recovery environments often have no or very limited communications infrastructure which poses a challenge to any communications system and makes the delivery of high-quality multimedia content extremely difficult. In order to ensure high-quality sharing of multimedia content between emergency teams a framework that is resilient, reliable, capable of handling dynamic behavior and able to handle multimedia traffic must be devised. This paper proposes a framework that combines peer-to-peer (p2p) streaming, Quality of Service (QoS) predictions, and geographic routing over WiFi wireless mesh networks to transmit high-quality multimedia content between early response teams in disaster recovery scenarios.

SP-driven QoS provision Mechanism for Real-Time Multimedia Streaming over P2P Networks using Admission Control

Enabling Quality of Service (QoS) for End-to-End real-time multimedia content delivery across heterogeneous P2P networks is challenging but vital for the efficient service provision. In this paper, we present an admission control based for the real-time multimedia streaming over Service Provider (SP) driven peer-to-Peer (P2P) networks. SP-driven P2P networks are the P2P networks where network p...
