This thesis aimed at studying the theoretical performance bounds of cooperative techniques in Body Area Networks (BAN). These networks are sensor networks, with a small number of nodes located on and inside the human body. Cooperative techniques are extremely dependent on the channel side information available at the time of transmission. Considering statistical information about the channel fading and the short-term mean of the signal, we derive an asymptotic approximation of the packet error rate under the so-called block fading channel model. Using this approximation, we can express in closed-form asymptotically optimal power allocation among transmitting nodesfor various models of relay channels. Under a complete channel knowledge hypot...
