In this paper, a delay tolerant approach for traffic management in LTE over satellite link is presented. Due to the long propagation delays and frequent disruptions, mobile satellite communications pose many challenges, especially to the transport layer when the TCP protocol is used. We design and evaluate the performance of a transport protocol solution based on the DTN architecture in the satellite-LTE...
With the proliferation of the Internet, voice over IP and multimedia communication become more and more important. One of the protocol that facilitated this development is Session Initiation Protocol (SIP). SIP is a signaling protocol which manages the session establishment and termination. It can be based on UDP or TCP at the transport layer. In this paper, the strengths and weaknesses of SIP over...
With the rapid development of the Internet, new technologies and applications are emerging. One of the important applications is voice over IP. Satellites are playing an important role to provide VoIP services with their global coverage and on-board processing ability over IP networks. Satellite network environment, generally characterized by large delay and erroneous link, is considered to be unfriendly...
In satellite networks, voice over IP performance is degraded by long delays and low bandwidth. Both call setup time and quality of service (QoS) for voice calls are affected. Separate studies have been undertaken for these performance metrics. In this paper, we have carried out experiments using different voice codecs to evaluate SIP call setup time and QoS parameters together. The experiments are...
IP multicast is a bandwidth efficient technology that can be utilised for one-to-many or many-to-many communications via satellite for aeronautical passenger communication. An AAA framework for multicast services was presented. The framework combines the GDOI multicast security protocol with AAA functionality enabling network providers to control access to multicast sessions and account the usage...
Transmission Control Protocol (TCP) is widely used transport protocol to provide reliable data delivery. It is the backbone protocol of most of the internet based applications. Importance of the TCP based applications in different networks with diverse conditions leads to the modifications and enhancements in basic TCP algorithm. In this paper, we evaluate the performance of TCP Tahoe, Reno, New Reno...
