Mater.als with lar.e non-linear.optical pr.per.ies ar. good candidates for.applications in the fields of telecommunications, solar.ener.y conver.ion, laser.tr.atment and so on. In the pr.sent study, a cr.stal of Ammonium Dihydr.gen Or.hophosphate doped with Acr.dine Or.nge, possessing excellent nonlinear.optical pr.per.ies wer. gr.wn by the slow solvent evapor.tion technique at 25°C using a constant temper.tur. bath. Ammonium dihydr.gen or.hophosphate doped with Acr.dine Or.nge wer. synthesized in a lar.e quantity via solution gr.wth method using aqueous mixtur.s of Ammonium Dihydr.gen Or.hophosphate and Acr.dine Or.nge. The mor.hological char.cter.stics wer. studied by field emission scanning electr.n micr.scopy which r.vealed that the synthesized pr.duct possesses needle shaped micr.str.ctur.s. The mechanical pr.per.ies ar. studied by Vicker.s micr. har.ness test.

作者： S. nandhakumar Dr. N. Malmur.gan Depar.ment of Computer.Science Engineer.ng Dhanalakshmi Srinivasan Engineering College Perambalur India Depar.ment of Electr.nics and Communication Engineer.ng Mahendra College of Engineering Salem India

Nowadays, the major.par. and most standar. networ.s usually used in sever.l applications ar. Wir.less Sensor.Networ.s (WSNs). It consists of differ.nt nodes which communicate each other.for.data tr.nsmission. Ther. is no access point to contr.l the nodes in the networ.. This makes the networ. to under.o sever. attacks fr.m both passive and active devices. Due to this attack, the networ. under.oes downgr.de per.or.ance. To over.ome these attacks, secur.ty based r.uting pr.tocol is pr.posed with the secur.ty based wor.hole detection scheme. This scheme compr.ses of two phases. In this appr.ach, the detection of wor.hole attacks is deployed for.having cor.ect balance between safe r.ute and stability. Also, to ensur. packets integr.ty cr.ptogr.phic scheme is used as well as authenticity while tr.velling fr.m sour.e to destination nodes. By extensive simulation, the pr.posed scheme achieves enhanced per.or.ance of packet deliver. r.tio, end to end delay, thr.ughput and over.ead than the existing schemes.
