Following a detailed overview of cooperative communications and the physical layer security, this book proposes relay and jammer selection schemes for security in one-way cooperative networks and to improve physical layer security in two-way cooperative networks. It also proposes a Cooperative Hybrid Self-Healing scheme to enhance the confidentiality of the data collected by UWSN. It ends with a proposal called Self-Healing Cluster Controlled Mobility (SH-CCM) scheme based on hybrid cooperation between both Proactive and Reactive peers and the sick sensors at both network and cluster levels to guarantee the security in UWSN.

2Overview of Cooperative Communications in Wireless Systems

2.1Introduction

The next-generation wireless systems are supposed to handle high data rate as well as large coverage area. It should consume less power and utilize bandwidth efficiently. At the same time, the mobile terminals must be simple, cheap, and smaller in size. In wireless environment, the quality of the received signal level degraded due to path loss, shadowing, and fading impairments. The effect of fading can be suppressed by any diversity technique. For example, spatial diversity can be achieved with the help of a multiple-input–multiple-output system (MIMO). However, implementing multiple antennas at a wireless terminal is not practical due to size, power, cost, and weight constraints. Thus, a virtual MIMO known as cooperative diversity is introduced. In cooperative wireless networks, the single-antenna mobiles share their antennas to transmit their data to the destination and therefore reap some of the MIMO benefits without physically deploying antenna elements.

This chapter highlights the main key contributions presented in the literature relevant to the problems studied in this book. Section 2.2 briefly describes the main characteristics of the wireless channels. Section 2.3 presents the different common diversity techniques in addition to an introduction to cooperative diversity. The concept of relay channel which considers the basis for cooperative communications is introduced in Section 2.4. A general overview on the cooperative communications working principle is given in Section 2.5. Section 2.6 describes the different cooperative protocols concerned with the processing of received source information at the relay nodes. Section 2.7 discusses the cooperative diversity based on relay selection. Section 2.8 highlights some of the areas where the cooperative relaying strategies can be applied. Finally, the pros and cons of cooperation are given in Section 2.9.
