Index Coding: A Greener Door for Wireless Networks

Wireless networks are at the heart of telecommunication technology. Energy constrained wireless devices in the high-data-rate communication era are pushing energy efficiency to the top of the priority list for the network design. Improving the throughput without compromising energy efficiency as well as spectrum usage is pivotal for greener wireless networks. This chapter focuses on the Index Coding problem that presents an important class of practical problems in wireless networks. The Index Coding problem opens up a green door for the communication paradigm in wireless networks. This chapter not only provides a comprehensive overview of the Index coding problem abut also presents its mathematical formulation, taxonomy, as well as several solution techniques.
