Disaster Management Issues in Ad-Hoc and WSNs with Healthcare and Communications Viewpoints
In recent years wireless ad-hoc and sensor network’s applications in disaster have drawn a lot of attention from both research and industry. Therefore, in order to improve the estimations that necessary for useful decision making for disaster personnel; this paper addresses disaster management issues in ad-hoc and WSNs with healthcare and communications viewpoints. We attempt to lift and discuss these issues and get some solutions to them. Accordingly, the theoretical bit error rate (BER) performances of four modes of quadratic-amplitude modulation (QAM) versus phase shift keying (PSK) is obtained, in which QAM performance is better than PSK. Moreover, the simulation results showed the BER performance of 16-mode for the two modulation techniques under AWGN and fading channel. According to the simulation results, we observed that at and in AWGN, the 16-QAM required 4dB less than PSK, but its performance in the fading channel not efficient. Furthermore, the evaluation of performance proves that the using of diversity order enhances the performance in the fading channel more and more.
