The First COST-IST(EU)-NSF(USA) Workshop on EXCHANGES & TRENDS IN NETWORKING

Introduction
Explosion of wireless devices and applications Eg. Cellular Networks, Ad Hoc Networks, Sensor
Networks Power hungry applications and shrinking form
Li-Ion polymer secondary cell, pulsed discharge, 2x useful energy increase vs continuous discharge (charge recovery)
Lithium coin primary cell, pulsed discharge, 8x useful energy increase vs continuous discharge
Pulse constraints for charge recovery: < max on time, >min idle time, <max idle current, high pulse current levels possible, 8x to 80x manufacturer’s recommended current
Improvement scenario: Same weight, same power, much more energy or Same weight, much more power, same energy
