Wireless sensor networks (WSNs) have attracted high interest over
the last few decades in the wireless and mobile computing research
community. Applications of WSNs are numerous and growing, including
indoor deployment scenarios in the home and office to outdoor
deployment in an adversary's territory in a tactical background.
However, due to their distributed nature and deployment in remote
areas, these networks are vulnerable to numerous security threats
that can adversely affect their performance. This problem is more
critical if the network is deployed for some mission-critical
applications, such as in a tactical battlefield. Random failure of
nodes is also very likely in real-life deployment scenarios. Due to
resource constraints in the sensor nodes, a traditional security
mechanism with high overhead of computation and communication is
not feasible in WSNs. Design and implementation of secure WSNs is,
therefore, a particularly challenging task. This book covers a
comprehensive discussion on state-of-the-art security technologies
for WSNs. It identifies various possible attacks at different
layers of the communication protocol stack in a typical WSN and
presents their possible countermeasures. A brief discussion on the
future direction of research in WSN security is also included.
Anesthesiology Critical Care Board Review fills a much-needed
niche, not only in improving board examination test-taking skills
but also as a tool for educating critical care physicians,
anesthesiology practitioners, and advanced practice providers with
the most relevant, up-to-date, state of the art considerations in
critical care medicine. Content is specifically designed to prepare
Anesthesiology and Emergency Medicine critical care fellows for the
American Board of Anesthesiology Critical Care Medicine
Certification Examination. The book offers diagnostic and
therapeutic management considerations, divided into sections on
technical aspects of critical care and organ systems, in a
question-and answer format with clear, concise explanations and
targeted references for each question.
