No. of difficulties involved that are facing for generating the nodes in the VANET and also the generating vehicular Ad-hoc network. In VANET having the vehicles different mobility pattern and also have the different direction and there is no constrains for the speed of the vehicles. In the Vehicular Ad-hoc Network the some vehicles are moving some are in the stationary position and some are in the high speeds so there is the problems of collision occur so in that case there is a need of the system which is used for the purpose of collision avoidance and detection and this is done by GPS (Global Position System) so for this situation there is a need to the network which is suitable for these purpose. The vehicular AD-hoc network is one of the most suitable future of the mobile Ad-hoc Network.

These states can be determined using various techniques apart from facial expressions. Acoustic parameters of a speech signal like energy, pitch, Mel Frequency Cepstral Coefficient (MFCC) are important in finding out the state of a person. In this project, the speech signal is taken as the input and by means of MFCC feature extraction method, cepstral coefficients are extracted by using MFCC. The large amount of extracted features may contain noise and other unwanted features. Hence, an evolutionary algorithm called as Ant Colony Optimization (ACO) is used as an efficient feature selection method. By using ACO technique the unwanted features are removed and only best feature subset is obtained. It is found that the total number of features extracted get reduced considerably. The software used is MATLAB

The unit has two alarm inputs and each one is monitored by a 2K2 resistor. If this input is either open circuit or closed circuit the input is considered to be in alarm. Similarly the set input is also monitored by a 2K2 resistor. The set input controls the isolation of the other two inputs.

Fuzzy logic is used to achieve smooth adaptations in duty cycles as well as to control the rate of adaptation. Proposed method helps reducing steady state oscillations and increasing convergence speed. SEPIC (Single Ended Primary Inductor Converter) is employed to realize appropriate output from proposed MPPT control. The limitation of SEPIC to track dynamic variations is overcome by fast operation of control algorithm. The system is simulated and tested in MATLAB/Simulink. Keywords—Maximum Power Point Tracking, Photovoltaic Systems, Fuzzy Logic, SEPIC Converter.
