Here a single antenna which is fundamentally inverted F antenna is used, the uniqueness of the design is that , it uses trap technique to produce dual resonance from a single inverted F antenna . The trap used to block the current due to some frequencies and passes the current contributed by other frequencies. So in short , this trap is like a RF filter which has some passband as well as stop band. This trap approach uses a LC network to achieve this design goal .The two bands of interest are 865-870 MHz and 902-928 MHz .. The challenge of this design is that the frequency separation of the two bands is very small. In this case, and also the extra section for low frequency band is too small. Then, the influence of trap LC component variation due to tolerance to the two resonant frequencies is big, and so it is difficult to achieve good in band return loss within the LC tolerance. This is the main difficulty of this design. This issue is resolved by placing the low band section away from the end of the antenna. The antenna is designed on FR4 substrate material having thickness of 1.6 mm and hence it is a low cost solution which could use in various commercial applications which follows these bands.","PeriodicalId":339265,"journal":{"name":"International Journal of Wireless & Mobile Networks","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125181445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 5G system relies on adaptive modulation and coding techniques to better suit the channel and maximize effective data exchange between the user equipment and the network. Practical studies on the behaviour of the system under different environmental conditions, subject to attenuation processes such as fading, are important to understand and improve the 5G efficiency. This work has analysed the effect of the MCS (Modulation and Coding Scheme) variation on throughput for channel degraded by the multipath fading effect in a mobile communication. The analysis was carried out showing that the decision algorithms in terms of MCS switching to maintain adequate data rates according to the requirement (QoS) is an important factor. Considering both 64 QAM and 256 QAM, the throughput degradation effect was more evident in higher-order modulations due to the higher probability of bit error in the symbol constellation. This study can be a key for understanding and developing robust MCS switcher for 5G and beyond communications.","PeriodicalId":339265,"journal":{"name":"International Journal of Wireless & Mobile Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122749405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MANET is a decentralized network that communicates without using any specified infrastructure. The lack of battery power in this multihop network with no infrastructure is problematic. As a result, proper transmission power utilization must be considered. Transmission power significantly impacts the data dissemination of different routing protocols used in this MANET environment. By taking this issue into account, the performance of routing protocols is examined based on different transmission power settings. The packet delivery ratio (PDR), packet loss (PL), jitter, and Dealy all play a role in determining network service quality. This study investigates how transmission power impacts MANET routing protocols’ quality of Service (QoS). The MANET routing protocols investigated in this study include AODV, OLSR, DSDV, and DSR. NS3 is used to create the simulation environment. According to this analysis, AODV outperforms other routing protocols in overall performance.","PeriodicalId":339265,"journal":{"name":"International Journal of Wireless & Mobile Networks","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127968007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet this objective, secondary research has been compiled as part of the analytic process. It was found from the research that IoT continues to evolve with significant degrees of proliferation. Complementary and trailblazing data mining (DM) with more access to cloud computing platforms has catalyzed accelerating the achievement of planned technological innovations. The outcome has been myriads of apps currently used in different thematic landscapes. Based on available data on app searches by users, and between 2016 and 2019, themes like sports, supply chain, and agriculture maintained positive trends over the four years. The emerging Internet of Nano-Things was found to be beneficial in many sectors. Wireless Sensor Networks (WSNs) were also found to be emerging with more accurate and effective results in gathering information along with processing data and communication technologies. In summary, available data indicate that IoT is happening and has a significant implication on data mining. All indications suggest that it will continue to grow and increasingly affect how we interact with “things”.

But the existing analogues to digital converters are efficient in processing signals with small to medium bandwidths, but inefficient for signals with large bandwidths. The real-time processing of these signals with large bandwidths are done analogically or optically at the cost of the aforementioned advantages of digital processing of these signals. This paper is aimed at solving the real-time challenge of processing these extremely wide bandwidth signals digitally using a compressive sensing (CS) algorithm, with specific detail on the ways the application of CS will enhance the energy efficiency of wireless communication devices. Consequently, determine the throughput at which the use of CS is energy efficient for wireless devices using energy-efficient compressive sensing throughput (EECST) model. The simulation results show that the throughput requirements for introducing CS in any machine to machine (M2M) / internet of things (IoT) communication application to be energy efficient are minimum of 54bits per second and 317 bits per second when the required number of clock cycles for performing various device applications is 20,000 and 50000 respectively.","PeriodicalId":339265,"journal":{"name":"International Journal of Wireless & Mobile Networks","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124637707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
