Hybrid surveillance system by using multi frequency bands enhancement

We present a new design of a surveillance system via hybrid network in which is integrate wire, wireless less, Ad hoc network, vehicular Ad hoc network, sensor network, and cellular wireless network. We propose the dense wavelength division multiplexing wavelength enhancement, whereas the increasing in channel capacity and signal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, whereas the security is introduced by the specific wavelength filter, which is operated by the central operator. The optical communication wavelength enhancement is reviewed. The advantage is that the proposed system can be implemented and used incorporating with the existed communication link in hybrid wireless system, where the privacy can be provided, which is discussed in details. © 2010 Wiley Periodicals.
