Experimental investigation on the effect of wavelength on aperture averaging in FSO communications
(The Optical Society, 2020-06-01)Atmospheric turbulence is a major impairment in free-space optical (FSO) communication systems. Based on the fact that the size of receiver aperture is much larger than operation wavelength, aperture averaging extracts ... -
Experimental QOS-based comparison of olsr and B.A.T.M.A.N. mesh routing algorithms for multimedia home networks
(2013-08)Wireless Mesh Networks (WMNs) allow communication of two nodes via a multi-hop route, without the need for an infrastructure such as base stations. Routing has been a fundamental issue for this type of communication networks. ... -
An experimental research on the effects of frost formation on different environmental conditions and surface configurations
Frost formation on finned surfaces is observed on heat exchangers in cooling systems such as refrigerators and air conditioners. Accumulated frost on finned surfaces blocks the air flow in between fins and reduces the ... -
