This paper propose a new design for a P2P overlay network over fiber optic communication that uses dense wavelength division multiplexing (E-DWDM) wavelength enhancement that can be used to generate the new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a MNRs, whereas the virtual P2P overlay networks are increased in channel capacity and signal security which can be provided. The increasing in number of channel can be obtained by increasing in the wavelength density, while the security is introduced by the specific wavelength filter, which is operated by the optical network and directly link with other nodes. The theoretical wavelength enhancement generation is reviewed. The advantage is that the proposed system can be implemented and used overlapping with the existed fiber optic communication link, where the privacy can be provided, which is discussed in details. © 2010 Published by Elsevier Ltd.

We present a novel system of a Gaussian soliton generation using a 1.30 μm optical pulse in a nonlinear micro-ring resonator system, which can be used to form the soliton pulse trains within the new wavelength band. By using the suitable parameters, the soliton pulse trains with the center wavelength at 1.30 μm can be generated after the intense Gaussian pulse is input into the nonlinear micro-ring resonator system. The initial pulse bandwidth is enlarged and the signal amplified by the nonlinear Kerr effects type within the ring resonator. The simulation values are used associating with the practical device parameters, whereas the obtained results have shown that the wavelength enhancement of the center wavelength can be achieved. Furthermore, the maximum soliton output power of 12 W is obtained, which is available to perform the long-distance communication link. The common problem of soliton dispersion is minimized by the zero dispersion condition in this case. The major advantage of the proposed system is that the dense wavelength division of the center wavelength with the spectral width of 7.0 pm (10<sup>-15</sup> m) and the free spectrum range of 400 pm can be generated and achieved. This is available for the used/installed wavelength enhancement, which can provide more available channel capacity in the existed public optical network. © 2009 Elsevier GmbH. All rights reserved.

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.
