Spontaneous Wireless Ad Hoc Networking: A Review

Communication in wireless network is based on client server model where an infrastructure is required between two clients or mobile to communicate with each other even though they are closed to each other. In human communication model, two people those are physically closed to each other can talk directly without any server. In spontaneous network there is no server or any infrastructure between nodes to communicate, anybody those who wants to communicate can join, communicate and leave the network without any central server. It is based on peer to peer network, where nodes can join and leave network and share or distribute information to each other like human communication model. As spontaneous network is self configured a security is a major concern. So a secure self configured protocol is required for user authentication, validation and data transfer. The existing system objective is the integration of services and devices in the same environment, enabling the user to have instant service without any external infrastructure. Secured protocol uses a hybrid symmetric/asymmetric key encryption scheme for user authentication and to exchange data. It is self configured as it is used to create and manage network, also manage resource sharing and providing services without any central infrastructure. In this paper, we study all work to be done on spontaneous network and various security mechanisms to be provided.
