Literature Review Title: Multimedia Internet of Things: A Comprehensive Survey 
Chapter Title:  I. ENERGY-AWARE AND GREEN COMMUNICATION 
1. Abstract of Cited Paper (BIB001):  Wireless multimedia nanosensor networks (WMNSN) are novel networks combining nanosensor technology and multimedia technology. They have wide application prospect in many fields. One of the major bottlenecks in WMNSN is the very limited energy that can be stored in a nanosensor. Thus, an energy harvesting multi-path routing protocol (EHMR) is proposed to solve this problem. In the protocol, a piezoelectric nano energy harvesting system is introduced to break the bottleneck. A game routing model is established to measure the contribution of a node to the path and the result decides which node will be selected as a next hop. The cooperative game routing model considers the energy consumption, the path's transmission rate, end-to-end delay and transmission success ratio. Simulation results show that this protocol can realize self-powered nanosensors and perpetual wireless nanosensor networks. Besides, it provides lower delay,higher transmission success ratio and throughput compared to greedy routing algorithm. And it is suitable for terahertz WMNSN.

Literature Review:
Energy is a scarce resource. Bandwidth and power-hungry multimedia applications require vast energy resources for their transmission. Thus, to transmit multimedia data over IoT, energy-aware and energy harvesting methods need to be explored. There are many energy harvesting solutions for harvesting energy from the environment. These solutions can assist in prolonging network life and promoting green communication BIB002 . SDNs provide a better softwarization and virtualization approach to manage hybrid energy resources in future communication networks BIB001 . To the best of our knowledge, SDNs are not studied for energy harvesting approaches to transmit multimedia content over the IoT network.
