| 1 | Metaheuristics Based Node Localization Approach for Real-Time Clustered Wireless Networks显示文摘In recent times,real time wireless networks have found their applicability in several practical applications such as smart city,healthcare,surveillance,environmental monitoring,etc.At the same time,proper localization of nodes in real time wireless networks helps to improve the overall functioning of networks.This study presents an Improved Metaheuristics based Energy Efficient Clustering with Node Localization(IM-EECNL)approach for real-time wireless networks.The proposed IM-EECNL technique involves two major processes namely node localization and clustering.Firstly,Chaotic Water Strider Algorithm based Node Localization(CWSANL)technique to determine the unknown position of the nodes.Secondly,an Oppositional Archimedes Optimization Algorithm based Clustering(OAOAC)technique is applied to accomplish energy efficiency in the network.Besides,the OAOAC technique derives afitness function comprising residual energy,distance to cluster heads(CHs),distance to base station(BS),and load.The performance validation of the IM-EECNL technique is carried out under several aspects such as localization and energy efficiency.A wide ranging comparative outcomes analysis highlighted the improved performance of the IM-EECNL approach on the recent approaches with the maximum packet delivery ratio(PDR)of 0.985. | R.Bhaskaran P.S.Sujith Kumar G.Shanthi L.Raja Gyanendra Prasad Joshi Woong Cho | 2023 | Computer Systems Science & Engineering2023，44，1： | 0 |
| 2 | Influence of field emission on microwave microdischarges显示文摘An instability in the stable operation of microdischarges sustained at microwave frequencies,is investigated by a self-consistent one-dimensional particle-in-cell Monte Carlo collisions model.The instability is caused by the field electron emission from electrodes and is triggered by the high electric fields at the sheaths in a dense microplasma.For an operating frequency of 9 GHz,and electrode gap of 60μm,the field emission(FE)is not active at the breakdown voltage.However,once a stable dense plasma is produced post-breakdown,a strong sheath results in an electrode electric fields that exceed the threshold for FE causing a runaway in the electron generation in the plasma. | Dmitry Levko Laxminarayan L.Raja | 2016 | High Voltage2016，1，1： | 0 |
