1. Introduction
Internet of Things is an emerging paradigm where various objects (or things) are able to connect to the Internet using technologies as wireless sensor networks [1], radio frequency identification [2], Wi-Fi [3] and cellular networks [4]. In a wireless sensor network, many sensor nodes are used to monitor physical or environmental conditions and utilize wireless communications to transmit information to each other [5]. An efficient strategy to cope with the impairments offered by the wireless communication channel is to employ a cooperative protocol between spatially distributed nodes. Several protocols, including amplify-and-forward (AF), decode-and-forward (DF), estimate-and-forward (EF) are widely used [6]. Since he sensor nodes have limited energy supply, energy effi- ciency is a crucial issue in the design of cooperative communication protocols. Optimal power allocation is an important question in performance enhancement of cooperative network protocols. In [7], the optimal power allocation and the associated symbol error rate performance were studied for AF and DF protocols under different modulation schemes. A similar investigation was done in [6] where the performance analysis and optimal power allocation for the EF protocol depend on the modulation scheme. Recently, optimal power allocation and adaptive modulation were used in AF cooperative protocols [8], where the objective was to find the signal-to-noise ratio (SNR) regions for adaptive modulation schemes considering a bit error rate (BER) constraint.
