The provision for addressing multiple destinations in group multimedia application delivery over Wireless Mesh Networks (WMN) can be achieved efficiently via multicasting while considering the mobility of Mesh Clients (MC). One of the prominent components of WMN is the Internet Gateway (IGW) which provides wired bridge connection between the backbone(More)
An efficient Erbium-doped fiber amplifier configured in doublepass amplification scheme with chirped fiber Bragg grating as the reflector is presented in this paper. The proposed amplifier architecture is optimized and designed to work under consideration of low pump powers for remotely-pumped applications. The chirped fiber Bragg grating is used to reflect(More)
Free Space Optics (FSO) link have capabilities of providing optical communications similar to fiber optics based communications. However, the operational status of an FSO link is highly weather dependent which hampered the FSO link with feasibility issue. Among the major effect on FSO links under local weather condition is due to attenuation of heavy(More)
Transducers have found wide applications in industries, though, they possess nonlinear responses. The nonlinearity feature does not prevail over the entire range; rather there are sections (or regions) on the response curves that are easily regarded as linear. This work focuses on analyzing transducer characteristics by finding regions exhibiting larger(More)
In an automatic fingerprint identification system (AFIS), the fingerprint enhancement algorithm is mainly used to improve the visual quality of the input fingerprint image. The factors affecting the quality of an input fingerprint image may be the presence of scars, cuts, pressure variation between the finger and sensor, worn artifacts, and humidity during(More)
There is increased deployment of portable IP-enabled devices and group content distribution applications on Wireless Mesh Networks (WMNs). This surge is facilitated by its relative low cost of installation and as such is an attractive option in environments lacking existing communication infrastructure and/or in times of natural emergencies. The WMNs is(More)
