The Anatomy of Wireless Sensor Networks provides readers with an in-depth discussion of what wireless sensor networks are their practical applications and their anatomy.  The anatomy of wireless sensor networks explained using a multidimensional approach. The first dimension focuses on wireless sensor nodes. The second dimension focuses on the networking aspect of WSNs and offers a comparison with the OSI model. The layers discussed within the ‘networking' section include the physical layer, the medium access layer, the network layer, the transportation layer and the application layer. The third dimension addresses the management aspect at various layers, focusing on power management, mobility management, time synchronization, task management and security.
