دانلود مقاله Secure and Efficient Intermediate Node Authentication in Wireless Sensor Networks

International Journal of Signal Processing Systems Vol. 3, No. 1, June 2015 R. C. Choukimath and V. V. Ayyannavar Abstract—Message authentication is one of the most effective ways to thwart unauthorized and corrupted messages from being forwarded in wireless sensor networks (WSNs). For this reason, many message authentication schemes have been developed, based on either symmetric-key cryptosystems or public-key cryptosystems. Most of them, however, have the limitations of high computationa ...

دانلود مقاله FAULT NODE RECOVERY ALGORITHM TO ENHANCE THE LIFETIME OF A WIRELESS SENSOR NETWORK - انتشار 2014

D.Suguna et al, International Journal of Computer Science and Mobile Applications,Vol.2 Issue. 8, August- 2014, pg. 06-14 D.Suguna,Dr. K.Elangovan AbstractThis paper proposes a fault node recovery algorithm to enhance the lifetime of a wireless sensor network whensome of the sensor nodes shut down. This algorithm is based on the grade diffusion algorithm combined with thegenetic algorithm. The algorithm can result in fewer replacements of sensor nodes and more reused routing paths. Inthis propos ...
