| Abstract | Energy Efficiency and Performance Analysis of Multihop Wireless Communication over Nakagami-m Fading Channels Itsikiantsoa Randrianantenaina It has been proven in the literature that the concept of multihop relaying (where the source communicates with the destination via many intermediate nodes) can improve wireless communications from multiple aspects such as broadening coverage, overcoming shadowing, reducing the transmit power, and increasing the capacity of the network at a low additional cost. On the other hand, the problem of energy efficiency is currently one of the biggest challenges for green radio communications. In fact, there has been a massive increase in the number of cellular network subscribers during the last two decades. Therefore, there has been an exponential expansion of the cellular network market, followed by an increase in the number of base stations that have costly energy requirements. In addition, for battery-powered devices, transmit and circuit energy consumption has to be minimized for better battery lifetime and performance. In this work, the performance of multihop relaying communication over Nakagamim fading is investigated without diversity combining as well as with. Closed form expression of the average ergodic capacity is given. Then, an expression of the outage probability is obtained using the inverse of Laplace transform and the average bit error rate is bounded using the Moment Generating Function approach. The energy efficiency is analyzed using the "consumption factor" as a metric, and it is derived in closed form for Amplify-and-Forward, and compared to the energy efficiency if Decode-and-Forward. Then, based on the obtained expressions, a power allocation strategy maximizing the consumption factor is proposed. Simulations and numerical results are presented to show the accuracy of the analysis, and the performance of the energy-aware power allocation scheme is compared, in terms of energy efficiency, as well as other common performance metrics, with other power allocation schemes from the literature. |
