Automatic creation and reconfiguration of network-aware service access paths

We evaluate the CANS infrastructure over a range of network and end-device characteristics using two application scenario: web access and image streaming. Our results validate the effectiveness of the CANS approach for enabling network-aware service access to mobile clients, verifying that (1) communication paths automatically generated by CANS bring considerable performance advantages to applications; (2) desirable adaptation can be achieved using our flexible path creation mechanisms, which consider both underlying network conditions and different performance preferences of applications; and (3) despite their flexibility, both run-time overheads of CANS communication paths and reconfiguration time are negligible for most applications, providing applications with agile adaptation to dynamic changes in networks.
