Cluster Head (CH) selection has a key role to maintain the energy level of the Wireless Sensor Networks (WSNs). Clustering and appropriate CH selection reduces communication overhead by using data aggregation, resulting in prolonged system life time. In this paper, homogeneous WSNs are considered where all the sensor nodes have the same energy. A Fuzzy Logic Based Control system is proposed which...
This paper focuses on methodology of optimization of the torque split and gear shift points in any drive cycle for Hybrid Electric vehicle. The methodology evaluates objective parameter defined at each and every operating point for Internal Combustion Engine (ICE) and electric motor-generator (E-machine) for all possible torque split and gear shift combinations at a particular instant and finally...
This paper presents the methodology and utility of an HEV plant model using Matlab-Simulink for testing the HCU (Hybrid control Unit) logics in dSPACE Hardware-in-loop environment. It also describes how requirements related to Hybrid Controller testing are addressed using the subject plant model. It further discuss about the requirements for Inputs to hybrid controller that are modeled in close loop...
The scientific facilities emitting ionizing radiation may have some significant failures and hazard issues, in and around their infrastructure. Significantly, this will also cause risks to workers and environment, which has led engineers to explore the use and implementation of mobile robots (MR), in order to reduce or eliminate such risks concerned with safety issues. Safe functioning of MR and the...
User cooperation technique exploits the diversity in wireless networks. In this paper, we have analyzed a hybrid FDMA-TDMA access technique in a cooperative distributive fashion introducing and implementing a modified protocol introduced. We have defined one parameter termed as cooperation gain parameter (CGP) which is the function of transmitter-to-receiver average received signal to noise ratios...
