This paper proposes an NDN-based message delivery protocol over a cellular network in disasters. Collaborative communication among cellular devices is integrated into the protocol so that power consumed by battery-operated base stations (BSs) is reduced when a blackout occurs. A key idea is to reduce consumed radio resources by making cellular devices of which radio propagation quality are better forward messages of neighboring devices. The radio resource reduction contributes to reducing power consumed by a battery-operated BS. We empirically and analytically evaluate how the proposed message delivery protocol reduces the power consumption of a BS assuming a densely populated shelter.

This paper proposes a sense amplifier for adiabatic memory using memristor. The proposed sense amplifier uses current rate sensing method. In simulation the proposed sense amplifier is to connect the content addressable memory (CAM) with adiabatic driving. From the results we show that the proposed circuit is correctly operated and its power dissipation is 36.1 pJ/cycle.
