The objective of this research is to explore a novel switching paradigm for WDM (Wavelength Division Multiplexed) optical networks, called optical burst switching (OBS). OBS uses an offset time between a control (or set-up) packet and its corresponding data burst when making one-way delayed reservation, which facilitates all-optical data transfers and distinguishes it from other one-way reservation schemes and label/tag switching schemes.

Research

The objective of this research is to integrate the cellular infrastructure with modern Ad-hoc relaying technologies to achieve dynamic load balancing among different cells in a cost-effective way.  The basic idea of the proposed iCAR (integrated Cellular and Ad-hoc Relay) system is to place a number of Ad-hoc Relay Stations} (or ARS) at strategic locations, which can be used to relay signals between MH's and base stations. By using ARS's, it's possible to divert traffic in one (possibly congested) cell to another (non-congested) cell.
