The rapid development of wireless and the advent of fixed mobile convergence have brought deployment of small wireless environment such as femtocell, which can connect Internet or network easily at home and office. Users must be authenticated from the Authentication, Authorization and Accounting (AAA) server to use the Internet or network at home and office. As diameter-based AAA uses TCP/SCTP at...
Wireless internet has become popular in recent years due to the tremendous growth in the number of mobile computing devices and high demand for continuous network connectivity regardless of physical locations. In this paper, we investigate the effects of routing protocols on the performance of Transmission Control Protocol (TCP) variants in multi-hop wireless networks. Through simulations we study...
Both the network mobility and the terminal mobility are likely to co-exist in the future. These two mobile communication paradigms have different wireless connectivity models and likely to deploy different schemes to address the wireless related performance issues for TCP. In this paper, we consider TCP Snoop, which allows a mobile terminal to efficiently recover from wireless-related losses. For...
Next generation heterogeneous networks require an effective handover scheme, optimized specially to support network mobility. The paper proposes an architecture to support seamless mobility of mobile networks across heterogeneous networks. We consider the vehicular scenario where a vehicle is provided with mobility through different Internet service providers (ISPs) and propose to use multiple mobile...
Internet access for highly mobile users in high-speed trains or cars, underground walkways and tunnels is often challenged by intermittent connectivity with short and unpredictable connectivity opportunities. In such opportunistic communication scenarios, utilizing these connectivity opportunities to the best potential for the mobile user can be crucial to achieve an acceptable overall perceived service...
Mobility of user devices connecting to the Internet is of major interest in today's research in networking. For users as well as for applications, network mobility should be transparent. Reliable transport protocols like TCP has served well the wired Internet where the packet losses are mainly due to congestion, but is not ready for mobile IP wired-cum-wireless environments where the significant packet...
Network mobility (NEMO) protocols can be used to manage aggregate mobility of multiple IP-enabled devices on-board a Low Earth Orbit satellite (a mobile network on-board). NEMO protocols enjoy several performance advantages, such as reduced signaling, increased manageability and conservation of satellite link bandwidth as compared to host mobility protocols for individual devices. In addition, NEMO...
Internet-on-the-train is a rising concept in the last few years. Several trials in different countries have proved the feasibility of offering Internet access to train commuters, but none of them combines broadband access, scalability, seamless handover and quality of service guarantees in one solution. In this paper, we look at the features of SCTP and its extensions which could overcome these shortcomings...
Network mobility (NEMO) basic support protocol is an extension mobile IPv6. NEMO signaling is performed with extended mobile IPv6 messages. NEMO basic support protocol is concerned with managing the mobility of an entire network, it provides for devices or vehicles which move to another point of attachment to the Internet. NEMO can maintain sessions established nodes between the mobile network and...
