[Although wireless sensor networks (WSNs) have been widely deployed to perform monitoring and surveillance tasks, their performance is highly deteriorated by energy and spectrum scarcities. By empowering sensors with energy and spectrum harvesting (ESH) capabilities, the emerging ESH sensor...
[This chapter provides a comprehensive survey of existing literature of energy and spectrum allocation regarding ESHSNs, to understand the issues related in a better way. We first survey the EH process modeling and energy allocation which provide insights for efficient utilization of harvested...
[In this chapter, we investigate the spectrum sensing and access of a heterogeneous spectrum harvesting sensor network (HSHSN) which consists of EH-enabled spectrum sensors and battery-powered data sensors. The former detects the availability of licensed channels, while the latter transmits...
[In this chapter, we develop an aggregate network utility optimization framework for energy and spectrum management in energy and spectrum harvesting sensor networks (ESHSNs). The framework captures three stochastic processes: energy harvesting dynamics, inaccuracy of channel occupancy...
[In this chapter, we conclude this book and discuss the future research directions.]
