Multimedia applications over the Internet and Internet Protocol Television (IPTV) gain a lot of attention. IPTV has a number of service requirements such as; high bandwidth, scalability, bounds on delay, jitter and channel zapping time. IP multicast, IP Multimedia System (IMS) Protocol and peer-to-peer (P2P) approaches are proposed for implementing IPTV. However, IP multicast requires all the routers in the core network to possess multicast capability, IMS does not easily scale and P2P cannot efficiently utilize the network resources because of its completely distributed nature. To this end, we propose Cluster Based Application Layer Multicast (ALM) IPTV (CALMTV) which is a new application layer multicast protocol for live IPTV. CALMTV combines application layer multicast, scalable video coding and probing techniques to meet live IPTV requirements. We present the components and their relevant algorithms of CALMTV. The performance of CALMTV is demonstrated with ns2 simulations. Our experiment results compared with the published results of other ALM architectures, which can support IPTV, show that CALMTV improves end-to-end delay and zapping time with respect to these architectures withou significant increase of jitter.

A New service architecture for IPTV over internet Özkardeş, Merve; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013) Multimedia applications over the Internet and Internet Protocol Television (IPTV) gain a lot of attention. IPTV has a number of service requirements such as; high bandwidth, scalability, minimum delay, jitter and channel switch time. IP multicast, IMS (IP Multimedia System) Protocol and peer-to-peer approaches are proposed for implementing IPTV. However, IP multicast requires all the routers in the core network to possess multicast capability, IMS does not easily scale and P2P cannot e ciently utilize the n...
Simulation-based VoIP performance evaluation under different traffic and codec conditions Ünlü, Berk; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013) One of today’s most popular multimedia applications that needs more investigation and optimization is Voice over Internet Protocol (VoIP). Simulation tools are essential to test existing network technologies and develop new ones. They are effectively used for network analysis and solving design and optimization problems. The focus of this thesis is an extensive simulation study to evaluate the achieved Quality of Service (QoS) support by VoIP traffic under different network topologies, traffic profiles, cod...
Video distribution over IP networks Özdem, Mehmet; Erten, Y. Murat; Department of Information Systems (2007) As applications like IPTV and VoD (Video on demand) are gaining popularity, it is becoming more important to study the behavior of video signals in the Internet access infrastructures such as ADSL and cable networks. Average delay, average jitter and packet loss in these networks affect the quality of service, hence transmission and access speeds need to be determined such that these parameters are minimized. In this study the behavior of the above mentioned IP networks under variable bit rate (VBR) video t...
GreenSlice: An Energy-Efficient Secure Network Slicing Framework Akin, Ozan; Gulmez, Umut Can; Sazak, Ozan; Yagmur, Osman Ufuk; Angın, Pelin (2022-02-01) The fifth generation of telecommunication networks comes with various use cases such as Enhanced Mobile Broadband, Ultra-Reliable and Low Latency Communications and Massive Machine Type Communications. These different types of communications have diverse requirements that need to be satisfied while they utilize the same physical infrastructure. By leveraging Software Defined Network (SDN) and Virtual Network Function (VNF) technologies, the 5G network slicing concept can provide end-to-end logical networks ...
Multimedia communication in wireless sensor networks Gurses, E; Akan, OB (2005-07-01) The technological advances in Micro ElectroMechanical Systems (MEMS) and wireless communications have enabled the realization of wireless sensor networks (WSN) comprised of large number of low-cost, low-power multifunctional sensor nodes. These tiny sensor nodes communicate in short distances and collaboratively work toward fulfilling the application specific objectives of WSN. However, realization of wide range of envisioned WSN applications necessitates effective communication protocols which can address ...
