Enhancement of sensor network lifetime based on simple transmission power control technique

A simple transmission power control technique has been proposed and demonstrated to realize an energy efficient sensor network over existing CATV infrastructures. The sensor network has been implemented by using the wasted bandwidth of the coaxial cables of a conventional CATV network and supports automatic transmission power control to enhance the network lifetime. The transmission power control technique can enhance the lifetime of sensor network by a factor of 1.7 times with a 42% improved power saving efficiency.
