“…The analysis shows that WLAN performance optimization is possible through optimal selection of different physical parameters (such as antenna configurations, guard interval between symbols, and modulation coding method) as a function of SNR. Various hybrid link adaptation proposals for WLAN [4] [19] [8] [6], succeefully improved the throughput of the system. However, our analysis shows that only the inclusion of multiple physical parameters in the link adaptation mechanism not necessarily gives better performance.…”

In wireless local area networks (WLANs), the data transmission rate is highly wavering concerning time according to changes in the channel environment. The traditional link adaptation algorithms, which rely on channel state information (CSI) estimation for selecting an appropriate modulation-coding scheme (MCS) does not thrive with madly varying channel conditions. To uphold this problem, in this paper we contemplate the link adaptation problem in IEEE 802.11n based WLAN by evaluating the performance under different combinations of transmission parameters or transmit modes. The evaluation results show that an optimal selection of transmission mode on a per-packet basis according to the current channel state maximizes the throughput performance of WLAN. Simulations over a wide class of TGn fading channel model shows that significant improvement in the throughput is possible by selecting an optimal combination of transmission parameters adaptively on a per-packet basis according to SNR estimation made at receiver.

“…When frequency hop is used alone, a high-throughput overhead and pre-sharing of key for channel selection is required. Similarly, to overcome jammer in rate adaptation (RA) [ 14 , 15 ], the transmitter forced to operate at the lowest transmission rate if jammer exists in between two legitimate users. So when these techniques are used separately, the performance shown is to be ineffective.…”

The healthcare industries research trends focus on patient reliable communication and security is a paramount requirement of healthcare applications. Jamming in wireless communication medium has become a major research issue due to the ease of blocking communication in wireless networks and throughput degradation. The most commonly used technique to overcome jamming is frequency hopping (FH). However, in traditional FH pre-sharing of key for channel selection and a high-throughput overhead is required. So to overcome this pre-sharing of key and to increase the security chaotic frequency hopping (CFH) has been proposed. The design of chaos-based hop selection is a new development that offers improved performance in transmission of information without pre-shared key and also increases the security. The authors analysed the performance of proposed CFH system under different reactive jamming durations. The percentage of error reduction by the reactive jamming for jamming duration 0.01 and 0.05 s for FH and CFH is 55.03 and 84.24%, respectively. The obtained result shows that CFH is more secure and difficult to jam by the reactive jammer.

Power transmission is the bulk transfer of electrical energy from power plants to sub-stations. A wireless sensor network is a promising technology for transmission line monitoring due to its low cost, easy installation, large-scale coverage, and fault tolerance characteristics. A wireless sensor network is application-specific; therefore, we investigate the new features and requirements of the wireless sensor network used in transmission line monitoring. Then, we propose an efficient wireless sensor network framework, which includes a clustering algorithm to simplify network management and to balance the network's energy consumption and a hybrid media access control (MAC) (H-MAC) protocol to handle traffic variability. The framework takes advantage of the features of network topology and traffic pattern to optimize the protocols' performance on real time and energy efficiency. The results indicate that the H-MAC shows a significant improvement in the network's reliability, real-time performance, and energy efficiency, and the cluster hierarchy can balance the network's energy consumption. Furthermore, the cluster hierarchy also prolongs the network's lifetime.
