The security of the virtual network will not benefit from using authentication method with the most promise for security unless both the way it is coded and the way it is implemented is equally as secure. It is essential to choose strong authentication algorithms which enforce good protection. The importance of the resource authentication process is the ability of the client to access and use the resource. A pseudo code was developed for the data center which is used to authenticate the client to use the resource. Our cloud infrastructure suggests using certificate based authentication for this sensitive access of the cloud. We can use encryption to protect stored passwords in the data center. We are using symmetric key algorithm, Advanced Encryption Standard with stretching the block size for this purpose. The data center does not keep all documents at one place. It keeps transposition the order of the documents in different virtual servers. There is no known attack for the Kerberos system till now which motivates us to involve this system to the cloud for resource authentication.

Public libraries are called the social institution that of the people by the people and for the people and it is always called ‘People’s University’ too as it provides education to all and to improve Information literacy, empowerment, and cultural heritage. This study has made an attempt to examine the current trends of user perception in terms of library services and availability of resources in public libraries in one of the western Tamil Nadu State particularly Tiruppur District Central Public Library. This study highlighted the various elements such as the gender and age wise distribution, Marital status and Educational qualifications, Occupation, and Membership, Residence, Availability of library resources, Frequency of Library visit, and Time spent in Library, Purpose of visiting the Library, Information search pattern, Level of satisfaction in terms of library services and resources were discussed. A total number of 200 questionnaires were distributed to the respondents who are actively participated at Tiruppur district public library. Out of 200 samples, we received only 177 dully filled questionnaires were returned. Further, all the valued data tabulated and interpreted with relevant statistical tools for better results.

Summary In recent years, mobile networks have been widely used in wide range of applications. Complexity is one of the major issues in mobile networks. The best way to administer the complexity of recent mobile networks is self‐organizing networks. Whenever a fault occurs in the network or in a node, it must be identified and at the same time, healed from within for smooth operation. In this paper, self‐healing is achieved by using a quadratic probing optimization algorithm. This algorithm has a time complexity using O (log n). A self‐healing algorithm is proposed here that uses self‐healing mechanisms to detect, identify, and respond to node breaks.
