Optimization of Disj.ints Using WDM-PON in an Optical Network

Circuits and Systems 2016年第9期7卷 2207-2216页

An optical network is a type of data communication network built with optical fibre technology. It utilizes optical fibre cables as the primary communication medium for converting data and passing data as light pulses between sender and receiver nodes. The maj.r issue in optical networking is disj.ints that occur in the network. A polynomial time algorithm Wavelength Division Multiplexing-Passive Optical Networking (WDM-PON) computes disj.ints of an optical network and reduces the count of disj.ints that occur in the network by separating Optical Network Units (ONU) into several virtual point-to-point connections. The Arrayed Waveguide Grating (AWG) filter is included in WDM-PON to avoid the traffic in the network thereby increasing the bandwidth capacity. In case of a failure or disj.int Ant Colony Optimization (ACO) algorithm is used to find the optimized shortest path for re-routing. For enhanced security, modified Rivert Shamir Adleman (RSA) algorithm encrypts the message during communication between the nodes. The efficiency is found to be improved in terms of delay in packet delivery, longer optical reach, optimized shortest path, packet error rate.

Asian Pacific j.urnal of Tropical Biomedicine 2012年第5期2卷 364-367页

作者： Samuel j.cob Inbaneson Sundaram Ravikumar Palavesam suganthi Department of Oceanography and Coastal Area Studies School of Marine SciencesAlagappa University

Obj.ctive:To identify the possible anliplasmodial compounds from Achyranlhes aspera(A. aspera).Acalypha indica(***),j.tropha glandulifera(***)and Phyllanlhus amarus(***).Methods:The ***,***,*** and *** were collected along Palk Strait and the extraction was carried out in *** filter sterilized extracts(100,50,25,12.5,6.25 and 3.125μg/mL) of leaf,stem,root and flower extracts of A aspera,A. indica,*** and *** were tested for anliplasmodial activity against Plasnuxlium *** potential extracts were also tested for their phytochemical ***: Of the selected plants species parts,the stem extract of *** showed excellent antiplasmodial activity(IC_(50)=43.81μg/mL) followed by stem extract of ***(IC_(50)= 49.14μg/mL).The stem extract of ***,leaf and root extracts of ***,leaf,root and seed extracts of j. glanduUfera and leaf and stem extracts of *** showed IC_(50),values between 50 and 100 μg/ *** analysis revealed that,significant antiplasmodial activity(Pj.ry to erythrocytes was also carried out and it showed that there were no morphological changes in erythrocytes by the elhanolic extract of all the tested plant *** in vitro antiplasmodial activity might be due to the presence of alkaloids,glycosides,***,saponins,triterpenoids,proteins, and lannins in the elhanolic extracts of tested ***:The elhanolic stem extracts of *** and *** possess lead compounds for the development of antiplasmodial drugs.
