Secured data transmission is a major concern in vehicular framework. The communication between vehicle-to-vehicle which helps in transferring of message. This survey was exposed to major attacks. Conventional safety techniques are based on key management and message encryption. The two techniques guarantee data transfer between source node and destination node in a secured manner. In vehicular framework, each and every vehicle acts as a source node as well as a destination node depending on the type of data. In the surrounding environment, it supplies the information between the stranger vehicles as well. This explains secure data is also transferred between malicious vehicles due to which interference makes much more complicated. In this paper, I want to carry out a brief survey on the VANETS and the secure message transmission methods which has been carried out so far. Though there are many techniques available, I want to analyze the problems which are faced during the implementation of VANETS and its secure transmission.

Multi-Agent System (MAS) architecture is a widely investigated topic for application in distributed control for power system operations. The key quality of MAS is its communication which must be versatile for any MAS based control. In this paper, a new communication algorithm for MAS based on Peer to Peer (P2P) communication agreeing to FIPA (Foundation of Intelligent Physical Agents) specifications is proposed. The proposed scheme has reduced communication steps, reduced burden on agents, and has very fast response compared to other existing P2P and Non-P2P architectures. This scheme is applied for a classic economic dispatch problem based on gradient search optimization and the simulation results are presented.

Unlike conventional drive system, torque as well as the power and speed can be directly Supplied to the wheel using a hub motor. This arrangement eliminates the gear and need for mechanical differentials. Outer -rotor type multi polar switched reluctance hub motor suited for many emerging Application for electric drive system. In this switched reluctance hub (SRHM) is controlled by two diode per phase provides (or) Asymmetric bridge converter. The high speed-coupler sensor used here provides an accurate measurement of actual rotor position necessary for proper commutation of our converter circuit.
