This book gives readers an in-depth analysis of the fundamentals behind designing on-demand medium access control (MAC) protocols for multihop wireless networks, esp. with nodes having multiple antenna technologies. This is the first attempt towards designing and analyzing on-demand, also known as contention-based, MAC protocols for multiple beam smart antennas (MBSA). The book begins with a general introduction of the state-of-art problems and solutions that then forms the basis of this book. The book then introduces mathematical models to analyze MBSA and derive basic MAC fundamentals. The...

Infection control in dentistry is never a topic with a limit. Every member of the Healthcare Professional/ dental team has a duty to ensure that all necessary steps are taken to prevent cross infection to protect both their patients and themselves. It is then necessary to strike a balance between cumbersome 'perfect' procedures and a reasonable approach, which is practical while minimizing the hazards to a point, where they present a negligible risk.
