Abstract:
Lifetime of wireless sensor networks depends critically on the available energy at the individual sensor nodes. However, constraints on the cost and physical size of low-complexity sensor nodes severely limit the battery capacity. Moreover, battery replacement can be impractical or impossible due to inaccessibility of remote sensor nodes, or their vast numbers. Harvesting the available ambient energy is a promising technology for sensor networks providing theoretically perpetual operation. However, in most cases harvested energy is limited in quantity and sporadic in availability, necessitating novel communication schemes to fully exploit the intermittent energy.
In this talk, we will overview different frameworks for the design of energy harvesting communication systems; in particular, we will consider offline, online and learning-theoretic approaches, which assume full, statistical and only model information about the underlying energy harvesting processes, respectively. Common mathematical tools and open problems will be presented for each framework. We will also consider the impact of various important practical issues such as battery leakage, processing energy cost and channel fading on the system design.
