Abstract

Recently, technological developments have enhanced, the use of Millimeter-wave (mm-Wave) Multiple Input Multiple Output (MIMO) system in various communication applications and wireless sensor networks as channel estimation efficiency can be immensely improved with the help of this technological developments in Millimeter-wave MIMO system and wireless sensor network as well. Moreover, they can improve quality of communication services to a great extent. However, cell interference in Millimeter-wave (mm-Wave) MIMO system can produce a massive impact on spectral efficiency. Therefore, a Routing Enabled Channel Estimation (RECE) technique is presented in this article to minimize interference between cells. The proposed Channel Estimation technique improves channel capacity as well as spectral efficiency. Moreover, Normalized Mean Square Error (NMSE) is minimized heavily using proposed RECE technique. Here, main aim of this article is to reduce cell interference and channel estimation inside a cell by using route selection, beam selection, and spatial frequency estimation. Here, different scenarios and parameters are considered to evaluate performance efficiency of proposed RECE technique in terms of spectral efficiency, NMSE and SNR and compared against varied traditional channel estimation techniques. Moreover, it is clearly evident from performance results that the proposed channel estimation technique performs better than the other two methods.

 #IJCNC #network #NetworkLifetime #RouteEstablishment #Security #WirelessSensorNetwork Hybrid Red Deer Algorithm with Physical Unclonable Function for Security Enhancement in IoT-WSN Authors Shilpa Venkata Rao and Vidya Anantha, Vivekananda Institute of Technology, India Abstract In this modern era, Wireless Sensor Network (WSNs) have turned out to be a more attractive option, because of the advancements in communication. If the network is insecure, an attacker can intercept messages and break the sensor nodes’ security; as well as duplicate the authentication codes to launch a variety of attacks. As a result, Physical Unclonable Functions (PUFs) with unpredictable features are encouraged to be used in the development of lightweight cryptographic protocols. This work introduced the Red Deer Algorithm (RDA) with PUF as a new mutual authentication system. When a sensor receives a challenge from the gateway, the inbuilt PUF generates a key and distributes it to the sensor by providing...

Salem1, Mohamed A. Aboul-Dahab2, Sherine M. Abd El-kader3 and Radwa A. Roshdy1, 1Higher Technological Institute, Tenth of Ramadan city, Egypt, 2Arab Academy for Science & Technology and Maritime Transport, Egypt, 3Electronics Research Institute, Egypt Abstract The benefits of Filter Bank Multicarrier (FBMC) make it an attractive waveform instead of orthogonal frequency division multiplexing (OFDM). However, a high peak-to-average power ratio (PAPR) is a significant drawback in FBMC. Exploiting a single carrier effect is considered an effective technique to reduce PAPR in FBMC systems with a small amount of additional complexity. Nevertheless, the PAPR reduction amount is different from the single carrier effect in the single carrier frequency division multiple access (SC-FDMA). T...

NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamic...
