An Efficient Prediction Based Clustering with CRCN

Vehicular Ad Hoc Networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) - the spontaneous creation of a wireless network for data exchange - to the domain of vehicles. Routing protocols are use to communicates between the nodes. After that we introduce the cognitive radio network. Cognitive radio is an intelligent radio that can be programmed and configured dynamically. Its transceiver is designed to use the best wireless channels in its vicinity. Such a radio automatically detects available channels in wireless spectrum, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given spectrum band at one location. After it we introduce predictive clustering approach. The task of predictive clustering combines elements from both prediction and clustering. Than allocate the Channel for the transmission of message. Communication starts between the nodes. We will use DSR protocol for routing.
