Wireless Sensor Networks: Current Status and Future Trends

Acquiring data from the deployment area of sensors is not always easy, with multiple issues to be considered in dealing with wireless sensor networks (WSNs). A major issue is the limited resources of the tiny sensor devices, which are run with one-time batteries. Even if rechargeable batteries are used, they are not always easy to replace once the sensors have been deployed. Though many of the issues have been solved, many still remain. This book presents basic information on WSNs, current and emerging trends in research and development, as well as future expectations for relevant areas.
