Previous analytical results on the resilience of unstructured P2P systems have not explicitly modeled heterogeneity of user churn (i.e., difference in online behavior) or the impact of in-degree on system resilience. To overcome these limitations, we introduce a generic model of heterogeneous user churn, derive the distribution of the various metrics observed in prior experimental studies (e.g., lifetime distribution of joining users, joint distribution of session time of alive peers, and residual lifetime of a randomly selected user), derive several closed-form results on the transient behavior of in-degree, and eventually obtain the joint in/out degree isolation probability as a simple …
Legal Issues: Security And Privacy With Mobile Devices, Brian Leonard, Maurice Dawson
Legal Issues: Security And Privacy With Mobile Devices, Brian Leonard, Maurice Dawson
Maurice Dawson
Privacy and security are two items being woven into the fabric of American law concerning mobile devices. This chapter will review and analyze the associated laws and policies that are currently in place or have been proposed to ensure proper execution of security measures for mobile and other devices while still protecting individual privacy. This chapter will address the fact that as the American society significantly uses mobile devices, it is imperative to understand the legal actions surrounding these technologies to include their associated uses. This chapter will also address the fact that with 9/11 in the not so distant …

Aligning information systems to corporate goals has emerged as a leading concern over the last couple of decades. It is essential that we understand the need for cloud computing and how this technology can be implemented. Through this literature review we review theories of cloud computing and further elaborate on the theoretical framework for the implementation of cloud computing technology across organizations. We also detail cloud computing implementations across various governmental organizations and also across the industry. This review is expected to provide the current study with a more practical perspective on the issues and complexities of using cloud computing …
