End-To-End Mobility for the Internet Using ILNP

Ditchaphong Phoomikiattisak, Saleem N. Bhatti
2019 Wireless Communications and Mobile Computing  
Our direct testbed performance comparison shows that ILNP provides better host mobility support than Mobile IPv6 in terms of session continuity, packet loss, and handoff delay for TCP.  ...  The current IETF Mobile IP standard relies on additional network entities for mobility management, can have poor performance, and has seen little deployment in real networks.  ...  This work was partially funded by the Government of Thailand through a Ph.D. scholarship for Dr. Phoomikiattisak.  ...

Performance comparison of 3G and metro-scale WiFi for vehicular network access

Pralhad Deshpande, Xiaoxiao Hou, Samir R. Das
2010 Proceedings of the 10th annual conference on Internet measurement - IMC '10  
It is conceivable that these properties can be judiciously exploited for a hybrid network design where 3G data can be offloaded to WiFi for better performance and to reduce 3G network congestion and to  ...  WiFi has frequent disconnections even in a commercially operated, metro-scale deployment; but when connected, indeed delivers high throughouts even in a mobile scenario.  ...  We note that using WiFi to reduce the load on 3G networks is not new, and has been promoted by both networking [10, 27, 4] and policy researchers [16, 13] .  ...

Opportunistic mobility with multipath TCP

Costin Raiciu, Dragos Niculescu, Marcelo Bagnulo, Mark James Handley
2011 Proceedings of the sixth international workshop on MobiArch - MobiArch '11  
Host mobility has traditionally been solved at the network layer, but even though Mobile IP has been standardised for 15 years, it hasn't been supported by operators.  ...  Using simulations and indoor experiments with WiFi and 3G, we show that MPTCP gives better throughput, achieves smoother handoffs, and can be tuned to lower energy consumption.  ...  Conventional solutions are crude; smart phones typically connect via one network at a time using a fixed policy such as "use WiFi if available, otherwise 3G".  ...

Enabling service adaptability with versatile anycast

Michal Szymaniak, Guillaume Pierre, Mariana Simons-Nikolova, Maarten van Steen
2007 Concurrency and Computation  
Note that implementing logical addresses in the network layer allows for leaving the higher layers of client-side software untouched.  ...  For example, differences in the utilization of individual grid nodes make it necessary to route client requests according to additional metrics such as network bandwidth and cpu load.  ...  Transferring the TCP connection state from one node to another is commonly referred to as TCP handoff. Note that TCP handoff does not affect client-side state.  ...
