Mobile Ad Hoc Networks (MANETs) are a popular form of network for data transfer due to the fact that they are dynamic, require no fixed infrastructure, and are scalable. However, MANETs are particularly susceptible to several different types of widely perpetrated cyberattack. One of the most common hacks aimed at MANETs is the Black Hole attack, in which a particular node within the network displays itself as having the shortest path for the node whose packets it wants to intercept. Once the packets are drawn to the Black Hole, they are then dropped instead of relayed, and the communication of the MANET is thereby disrupted, without knowledge of the other nodes in the network. Due to the sophistication of the Black Hole attack, there has been a lot of research conducted on how to detect it and prevent it. The authors of this short format title provide their research results on providing an effective solution to Black Hole attacks, including introduction of new MANET routing protocols that can be implemented in order to improve detection accuracy and network parameters such as total dropped packets, end-to-end delay, packet delivery ratio, and routing request overhead.

  • Elaborates on the basics of wireless networks, MANETs
  • Explains the significance behind the need of wireless networks and MANET security
  • Understand MANET routing protocols, namely the ADOV method

Since its first publication, almost two decades ago, A System of Orthopaedic Medicine has proven to be a reliable resource and guide for those clinicians working in the field of orthopaedic medicine who assess and treat the effects of musculoskeletal pain.

This third edition remains focused on clinical reasoning and diagnosis, with detailed guidance on palpation of the anatomical structures and the correct performance of each therapeutic technique. Following the ‘System’, the clinician first completes a systematic clinical assessment of the joints involved, and then, after interpreting the results, groups the disorders and conditions into clinical syndromes. Finally, the natural history and the conservative treatment of each condition are discussed accordingly.

NEW! Building on the previous edition, A System of Orthopaedic Medicine now comes with access to online resources designed to support and enhance the learning experience of each and every clinician using the book. The new edition has been streamlined for easier access and handling by transferring all the applied anatomy chapters, references, links and other selected chapters onto the online resources.

LOG ON TO www.orthopaedicmedicineonline.com TO START YOUR EXPERIENCE AND ACCESS:

  • x100 video clips of examination and treatment techniques (referenced in the book)
  • all the references with access to the abstracts on Medline
  • online only chapters which includes applied anatomy (referenced in the book)

A Territorial Antelope: The Uganda Waterbuck discusses anatomical, physiological, and behavioral organization from birth to death of waterbuck. Comprised of 12 chapters, the book focuses on the function and cause of the waterbuck’s territorial behavior.
After an introduction to the classification, distribution, and origins of waterbuck, the book discusses the topography, geology, vegetation, fauna, and methods of evaluation of this species. The following chapters focus on the biological aspects of waterbuck, including its growth and senescence; reproduction and reproductive behavior; and parturition and maternal behavior. The book also deals with the role of food supply and habitat preference in population density and survival of waterbuck. Discussions on the activity rhythm, movement, reaction to predators, and relationships with other species of waterbuck are also included. The concluding chapters describe the diverse and complex social organization of this animal. These chapters also cover the territorial concepts and function, territorial boundaries, and repression of aggression behavior of waterbuck.
This book is an invaluable source for biologists, researchers, teachers, and students who wish to gain insights on the mechanisms of territorial behavior.

A Textbook of Plant Virus Diseases deals with a discussion of different plant viruses, their properties, and the corresponding diseases these viruses cause. It includes a list of host plants of every virus arranged alphabetically.
The book discusses the new types of disease vectors, such as root-infesting fungi, nematode worms, mites, and insects that are both biting and sucking. It also discusses the development of new techniques in electron microscopy that is used to characterize in detail the causal viruses of a number of plant virus diseases. Furthermore, it presents the development of plant virus serology, as well as the improved methods of virus isolation that allow the classification of viruses into related groups.
The book includes a Bibliography and an Index of Synonyms that can be used in identifying given virus name. In addition, cross-references are included for searching a particular virus under the alternative names.
This book will be invaluable to ecologists, environmentalists, agriculturalists, and other scientists interested in plant viruses. Biology students will also find this reference helpful.
