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

Designing and

network mobility

(NEMO) with fast

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
