This book covers the theory, design, and applications of computer networks, distributed computing, and information systems. Today&s networks are going through a rapid evolution and there are many emerging areas of information networking and their applications. Heterogeneous networking, supported by recent technological advances in low power wireless communications along with silicon integration of various functionalities such as sensing, communications, intelligence, and actuations, is emerging as a critically important disruptive computer class based on a new platform, networking structure, and interface that enable novel, low-cost, and high-volume applications. However, several applications have been difficult to realize because of many interconnection problems. To fulfill their large range of applications, different kinds of networks need to collaborate and integrate wired and wireless systems to develop high-performance computing solutions to problems arising from the complexities of these networks.  The aim of the book is to provide latest research findings, innovative research results, methods, and development techniques from both theoretical and practical perspectives related to the emerging areas of information networking and applications.
