ABSTRACT
This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book describes the basic impairments of the wireless channel. It discusses the multiple-input-multiple-output system model as a spatial diversity-based model that aims to enhance the data rate and the transmission reliability. In addition, the security in the wireless networks is handled to protect the transmitted messages against interception by unauthorized malicious receivers that lie in the coverage area of the transmission. Mobility does not disturb the number of neighbors per sensor and the network coverage. The book discusses various relay and jammer selection schemes to improve the physical layer security in one-way cooperative networks. It discusses impact of changing both the eavesdroppers and the intermediate nodes' location on the system's performance. The book describes the basic principles of the Wireless sensor network. It also discusses the impact of the presence of multiple cooperating and noncooperating eavesdroppers on system performance metrics.
