    Techniques for minimizing bandwidth bottlenecks in wireless networks for electromagnetic compatibility /
    (IEEE, 2024-06-24) Srividhya, S.
    Wi-Fi networks can face electromagnetic compatibility (EMC) issues due to bandwidth bottlenecks., various strategies were evolved to limit the bandwidth constraints while growing the throughput of Wi-Fi networks. These strategies vary from channel get admission to protocols, dynamic channel challenge schemes, and superior medium get entry to manage (MAC) protocols to radio resource management schemes (RRM) and active interference cancellation (AIC). Properly implementing those strategies can result in stepped-forward conversation overall performance and more advantageous network throughput. This paper presents a top-level view of the different strategies to reduce bandwidth bottlenecks in Wi-Fi networks, focusing on EMC. An analysis of the most enormous advocated techniques proposed for mitigating the clash between the electromagnetic environment and technological constraints is provided. In the long run, it’s proposed that after being carried out synergistically, strategies such as channel get right of entry to protocols, dynamic channel allocation schemes, RRM, and AIC protocols can enhance the throughput of Wi-Fi networks while keeping electromagnetic compatibility.

    Correlation between propulsion engine with propulsor for fishing vessels – a mathematical approach /
    (IEEE, 2022-02-21) Narayanan, Jayagopal; Murthy, Yvv Satyanarayana; Balaji, Rajoo; Ghosh, Surajit; Hulmani, Ram M.
    The energy efficiency is of most important in all economical activities for the fishing industry, energy efficiency can be expressed in term of the ratio of fishing capture over operational cost. The fuel cost and maintenance cost in fishing vessel operation became a dominant factor of the total operational cost. Moreover, fuel cost is high and continues to increase. Each region in India follows unique methods of vessel construction and fishing methods. Also, vessel speed requirement of the regions and the type of fishing are diversified. One way to achieve best energy efficiency is highly depends on the optimum selection of engine and the propeller for the vessel. This research aims to estimate the optimal common mathematical simulation approach for matching propulsion engine along with propeller for the fishing vessel by considering all variables such as hull profile, fishing methods, operating pattern, resistances and appendix as an influencing function. The method and operation pattern of Cruising, Trawling, Purse seine, Gillnet, Long line are taken into consideration for all mathematical simulation. In addition to mathematical simulation this report also covers the practical verification and validation of actual on-board performance on all selected type of fishing vessels, methods, grounds and fishing operations.
