“…The authors in research papers [15,16] present state of the art techniques and methods for improving wireless communication but they are not focussed on the BAN. The work discussed prior in [14] and [17] are some of the works have specially focussed on BANs but they take into account the 2.36 GHz band.…”

Body area networks (BAN) are a new variety of wireless sensor networks which are being developed to track patients' health. The 3.1-10.6 GHz ultra wideband band based BAN design has received huge commendation due to its capacity to provide high data rates and ability to carry medical signals of high bandwidth, on the sombre side however, its range is restricted in the human body channel. It requires novel techniques to improve the reliability and range. This paper proposes a novel approach to this problem. A solution using cooperative relaying has been proposed, that is not only unique, but also superior to classical cooperative relaying techniques. A cooperative relaying scheme employing hybrid relays, capable of a combination of 'Amplify and Forward' and 'Decode and Forward' relaying is used. In this method the signal to noise ratio, and mean square error, for electrocardiogram, blood pressure, electroencephalograms, and peak signal to noise ratio for magnetic resonance images, retinal and iris images, are measured at the relay and a decision is made to select relaying strategy. The work is unique in the aspect that, simulations have been performed and a comparative performance is presented, which suggests that SNR improvements of at least 3 dB, and quality of received medical signals is vastly enhanced.

“…The interaction between the BS and users was modeled as a Stackelberg game and a novel price-based power control algorithm for the base station of primary users was proposed in [15] to solve price-based power control problem in cognitive radio networks whose spectrum is shared. In [16], the power control problem for cooperative communication networks was studied by analyzing the cooperation behavior of selfish user nodes with cooperative games.…”

“…There have been quite a few papers which studied on power allocation in wireless networks, such as [14]- [16]. In [14], by employing a Stackelberg game between the source node and the relay nodes, Wang et al achieved optimal relay selection and power allocation without knowledge of channel state information in multiuser cooperative wireless networks.…”

As wireless networks are vulnerable to malicious attacks, security issues have aroused enormous research interest.In this paper, we focus on the anti-jamming power control of transmitters in a cooperative wireless network attacked by a smart jammer with the capability to sense the ongoing transmis sion power before making a jamming decision. By modeling the interaction between transmitters and a jammer as a Stackelberg game, we analyze the optimal strategies for both transmitters and the jammer and thus derive the Stackelberg equilibrium of the game. In addition, the Nash equilibrium of the anti-jamming game is also derived to compare with the Stackelberg equilibrium strategy. Finally, the impacts of the fading channel gains of the transmitters and the jammer on their utilities and the SINR are measured, respectively. Simulation results are presented to verify the performance of the proposed Stackelberg equilibrium strategy.

In this paper, we investigate the statistical characteristics of the equivalent end-to-end signal-to-noise ratios (SNRs), the average symbol error ratios (SERs), and the optimal power allocation (OPA) for two-way amplify-and-forward opportunistic relaying (TWOR-AF) systems. First, with strict mathematic manipulation, we obtain the closed-form solutions to the PDF, CDF, and moment generating function of the end-to-end SNRs. Then, based on the obtained statistical results, we present the total average SER of the Non-OPA TWOR-AF systems by using the appropriate approximation, in which only the greater segment of the two terminal SERs is considered. Finally, by aiming at minimizing the total average SER and using the SNRs balancing condition at both transceivers, we study the OPA problem subject to a total transmission power constraint. The comparison analysis shows that, for the Non-OPA TWOR-AF systems, we can only evaluate exactly the greater segment of the two SERs of the received signals at two transceivers by using the derivations. However, for the OPA TWOR-AF systems, with our derivations we can evaluate exactly not only each segment of the two terminal SERs but also the sum SER (exact total SER). Moreover, the simulations show the OPA TWOR-AF systems outperform the Non-OPA TWOR-AF systems.In [12], Barua et al. studied the OWOR-AF systems. In the work, authors have presented the statistic descriptions of the instantaneous end-to-end signal-to-noise ratio (SNR), including the CDF, PDF, and moment-generating function (MGF). With the obtained closed-form solutions to the statistic descriptions, authors have investigated the symbol error rate (SER) of the OWOR-AF systems and the comparison between OR schemes and no OR schemes. In [13], authors investigated the SER performance of one-way partial relay selection AF systems by using the statistical results presented in [12].For TWOR-AF systems, it has been investigated in the literatures [14][15][16]. In [14], authors treated both instantaneous end-to-end SNRs as two independent random variables (RVs), and presented the outage probability. However, in [15], authors pointed out that the results given in [14] are not right because the two end-to-end received SNRs are dependent, essentially. Therefore, authors restudied the TWOR-AF systems in [15], and presented the exact solution to the outage probability in integral form and the corresponding lower bound closed-form solution. In these existing works about TWOR-AF, only the outage probability has been studied without the one of average SER. It is well known that the average SER of digital communication systems over fading channels can be determined easily by using the MGF-based approach. However, observing the contributions presented in [14-16], we find that it is impractical or difficult to obtain the exact closed-from expression of SER because the exact statistic descriptions have been given by very complicated formulations in these works. Fortunately, in [14] Zheng et al. presented the approximate lower bound estimat...
