Enhance Security for Spontaneous Wireless Ad Hoc Network Creation In An mobile ad hoc network must operate independent of pre established or centralized networkmanagement Infrastructure, while still providing administrative services needed to support applications. Address allocation, name resolution, service location, authentication, and access control policies represent just some of the functionality that must be supported – without pre configuration or centralized services in this paper spontaneous wireless ad hoc network creation no need of any infrastructure no need of any administrator for handling the services. No need of any external support for handling functionalities of network. All the services are provided without fixed infrastructure whoever is present in the network. This protocol allows sharing of resources and services among users in secure environment. 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. In this paper, we study all work to be done on spontaneous network and various security mechanisms to be provided.
