“…The CATV network in house and building is usually configured as the multiple star architecture where the cascaded splitters are used to distribute CATV signal from central node to rooms or offices [2]. Since the coaxial cable deployed for the CATV service has sufficient bandwidth to accommodate other services, the sensor network can be implemented by using CATV infrastructure.…”

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.

“…Furthermore, though the sensor node of the wireless sensor network can be powered from a small battery, one should monitor the state of the battery and need to replace or recharge a worn-out battery to guarantee a reliable operation of the wireless sensor network. This problem consequentially increases the maintenance cost of the sensor network.Recently, we had proposed and demonstrated a novel sensor network technology by using the CATV infrastructure in order to overcome the problems of the wireless sensor network used in indoor environment [4].

The CATV infrastructure has been deployed in most houses and buildings and the coaxial cables of the CATV infrastructure usually can provide sufficient bandwidth to accommodate other services as well as CATV service. We have proposed and demonstrated a novel remotely powered sensor network over the existing CATV infrastructure composed of coaxial cables, splitters and so on. The proposed sensor network has been implemented by using the wasted bandwidth of the coaxial cable (VHF and UHF bands) of the conventional CATV network without any change of the existing infrastructure. Furthermore, it supports a convenient remote power feeding from a central node to end nodes (sensor nodes) by using coaxial cable. We have developed transceiver for the wired sensor network matched the characteristics impedance of the coaxial cable of the CATV network. We also have developed protocol stack of the transceiver to interface with wired cable instead of air and to support the remote power feeding to the end nodes. We have confirmed the performance of the proposed sensor network by measuring the packet error rate (PER) for various data rates when the end nodes were remotely powered. The maximum transmission distance between the central node and the end node of the wired CATV network was about 265 m when the 128 sensor nodes were joined the network at the operating data rate of 250 kb/s. The wireless sensor network can be easily deployed for various applications since it does not require wire-based infrastructure.ost applications of sensor network focus on sensing and controlling for military, industrial and indoor applications. The advantage of sensor network is mostly characterized by its low power consumption, low cost based on low data rate and highly reliable networking for sensing and controlling signals [1-3]. However, the wireless sensor network can suffer from the interferences with other wireless networking services, the poor networking security and the relatively higher power consumption compared with wired connection. Especially, when the wireless sensor network is deployed indoor applications in houses or buildings instead of open space applications, the problems become more severe [2]. Furthermore, though the sensor node of the wireless sensor network can be powered from a small battery, one should monitor the state of the battery and need to replace or recharge a worn-out battery to guarantee a reliable operation of the wireless sensor network. This problem consequentially increases the maintenance cost of the sensor network.Recently, we had proposed and demonstrated a novel sensor network technology by using the CATV infrastructure in order to overcome the problems of the wireless sensor network used in indoor environment [4].
