Protocol complexity, node deployment, heterogeneity, requirement of GPS device, etc are major issue for a given system model. The CGDC protocol saves the extra cost by allowing homogenous network, with no GPS requirement and a simple model for the protocol implementation. The system also provides application of protocols in a wide range of domains. In this we discussed the lifecycle of the protocol in short and also the algorithm proposed for the group formation. In addition to this it also mentioned the data communication in steady phase towards the BS in a multi-hop manner. The CGDC...
