A new routing protocol which is used in wireless sensor network is ACO. It does the optimization process and generates a new way for energy efficient data transmission. This process will overcome the loss and drawbacks in fuzzy logic process which uses clustering. In fuzzy logic process, the LEACH algorithm is being used which requires a large amount of time and energy. But ACO works in contradiction. Sybil Attack is a type of attack seen in peer-to-peer networks in which a node in the network operates multiple identifies actively at the same time and undetermines the authority/power in reputation systems. Message such as the data gathered via one node is sent to another node that is within the particular surrounding. The data togetherized are the information like if there is any damage in the roads or any accident that had been occurred and cause traffic. The Existing system has the disadvantage of Sybil attack, and can be able to send messages to the vehicles nearby only if the vehicle is in static and it is difficult to find the distance between one node to another and to send data packets if the vehicle (generally cars) is in move. The proposed system detects the data and sends messages to the cars even if it is dynamic by creating a virtual node and removes the old data that is received before thereby overcoming the disadvantage of Sybil attack in the Existing system. Also the proposed system send the data packets to the vehicles that is surrounding the particular range greater than the range in the Existing system.
