In this paper, we propose a fully-integrated SIP+HCoP-B architecture to provide efficient mobility management of the nested mobile network. It achieves the following merits as compared to traditional SIP over NBS and SIP over HCoP-B architectures. First, it reduces network deployment costs by only equipping an integrated SIP mobile server, instead of both SIP home registrar and Mobile IP home agent, for each mobile router. Second, it achieves the smallest signaling overhead and the shortest session initialization latency. Finally, it supports both SIP-based and non-SIP-based applications.

A three-dimensional electrodeless dielectrophoresis (EDEP) device incorporating a micrometer-sized constriction region is proposed for the rapid preconcentration of protein. The electrokinetic phenomena within the proposed device are investigated both numerically and experimentally. It is shown that the micro-constriction structure increases the field-focusing factor by around 15 000 times and yields a 106-fold increase in the concentration of streptavidin protein within 36 s. Overall, the proposed device provides a low-cost and effective solution for performing highly-sensitive protein detection and overcomes the Poisson statistical limit inherent in traditional two-dimensional (2D) EDEP devices through its support of large (ml-scale) sample volumes.

In the past, we have proposed a fully-integrated SIP+HCoP-B scheme to provide efficient mobility management of the nested mobile network. In this paper, we extend our previous works by adopting the analytical model proposed in [1] to investigate performances of SIP+HCoP-B and other wellknown schemes over error-prone wireless links. Based on the radio link protocol to detect packet losses and performs retransmissions on the wireless link, we first analyze performance metrics and then perform numerical calculations for them. Consequently, SIP+HCoP-B achieves the shortest session initialization and handoff latencies, which exhibits its benefits on supporting SIP in the nested mobile network even over error-prone wireless links.SIP+HCoP-B; nested mobile network; radio link protocol; frame error rate; performance analysis
