The major advantage of WSN is that it can be installed in harsh environment such as in volcanic eruption, seismic regions, battlefield and forest, etc. The sensor nodes are generally battery-powered devices, the key task in WSN is to reduce the energy consumption of nodes so that the lifetime of the network can be augmented. Energy efficiency and information gathering is a major concern in many applications of WSNs. Many techniques have been developed till now in order to achieve an energy efficient network. Hierarchical clustering is an effective method to save energy in WSNs. Some of the most common energy-efficiency sensor networks protocols is Low Energy Adaptive Clustering Hierarchy (LEACH) as source. In this paper, we propose Threshold sensitive Low Energy Adaptive Clustering Hierarchy for Wireless Sensor Networks (T-LEACH). This last considers the node's heterogeneity of nodes and residual energy for choosing the optimal cluster head (CH). The simulation results have clearly shown that T-LEACH reduces the node's energy consumption, improves the network lifetime and packet transfer ratio.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116628113","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 followed technique relies on transforming the impulsive hybrid nonlinear dynamics of the passive motion into a linear form around a period-1 limit cycle. Forward, we simplify the complicated resulted expression using the second order of the Taylor Series. This technique, enables us to design a closed form of the CPM. The control of the passive bipedal locomotion starts with the identification of the period-1 fixed point of the non-CPM and continues with the determination of the linearized PM around such fixed point. Next, a feedback controller is adopted to stabilize this identified fixed point. Some simulation results are provided at the end to illustrate the efficiency of the control process of the passive walking motion of the compass-gait robot model.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133532202","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}
