Beschreibung
This book examines the handoff problem of cellular networks in Part I and the Power management problem of sensor networks in Part II. Both problems are key issues in resource allocation and in ensuring quality of service in the respective applications of wireless networks. Handoff from one serving base station to another occurs when certain conditions on signal quality at serving base station are not met. Power management in sensor networks ensures that sensors last longer, and therefore the required quality of information collected from sensors is achieved. Part I will show the inadequacy of existing criteria for comparing handoff methods considering many factors that influence quality, and develop a realistic and comprehensive criterion to do so. Part II focuses on developing a comprehensive energy model for sensors and their use to enable new strategies for power management in sensor networks. The work provides guidelines for efficient and reliable sensor network design that can be used to optimize energy efficiency subject to required specifications. It proposes High Powered Cluster Heads to increase the sensor network lifetime.
