Cloud computing is a computing paradigm, where a large amount of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. It can be defined as a new style of computing in which dynamically scalable and often virtualized resources are provided as a services over the Internet. Cloud storage allows user to upload the application and download it. However, the users no longer have physical possession of the outsourced data, it formidable task to maintain the data integrity protection in cloud computing, especially for users having constrained computing resources. Moreover the user should not worry about the integrity of the data and should use the cloud storage. The user uses the Third Party Auditor (TPA) who verifies the integrity of the data and sends the result to the user upon the request. The user can access the data without the online burden of verifying it and use the data without any worries. The Trustworthiness of the TPA is verified so that the cloud user does not have any fear of sending the request to an untrusted entity. Moreover the localization of the error is specified such that the misbehaving server is identified such that the user can easily modify the data for further use if required.

Wireless technology is gaining importance with enhancement in internet technology. Mobility is the key feature of wireless technology which allows users to continue ongoing sessions seamlessly. To achieve seamless communication between mobile nodes various mobility management protocols have been standardized for IPv6 by IETF. MIPv6 is the basic protocol based on host based mobility management which requires mobile nodes involvement in handover signaling. To improve MIPv6, new extensions as FMIPv6 and HMIPv6 FHMIPv6 were proposed. FMIPv6 works in predictive as well as Reactive mode. During signaling Packet loss may be occur. It is a key parameter which is variable with respect to different protocols. During handover packet loss is due to discontinuity in connection. In this paper we are focusing on total packet loss in host based mobility management protocols: MIPv6, FMIPv6 (Predictive and Reactive), HMIPv6, FHMIPv6 We are proposing and analyzing formulae for packet loss in these protocols. Also we will make numerical analysis and comparison for these host based mobility management protocols.
