Modeling UMTS Power Saving with Bursty Packet Data Traffic
Previous work on Power Saving assumed Poisson Traffic (Zheng, R., Hou, J.C. and Sha, L., University of Illinois at Urbana-Champaign)
Our work proposes a general model for bursty packet data traffic
Supporting seamless
vertical handoff for next
generation heterogeneous
all-IP 4G systems by
utilizing the multi-homing
feature of SCTP
Previous works select an
appropriate transmission
path based on the signal
strength, bandwidth or
round trip time delay (V. C.
M. Leung, University of
British Columbia)
Our work designs criteria to select
the best transmission path by
considering the bandwidth, round
trip time delay and power
consumption at the same time

mobile IP (FMIP)
capability over next
generation
heterogeneous all-IP
4G systems
Previous works consider the issues for NEMO and FMIP independently. The NEMO without FMIP layer-2 support usually suffers from significantly long delay, which is intolerable for real-time multimedia applications (M. Calderón, Universidad Carlos III de Madrid)
Our work designs and implements mechanisms to integrate NEMO with FMIP and resolves the resultant tromboning routing
