Selfish node detection in packet routing for MANET using global watchdog

Abstract

WSN is the most frequently used network for better scalability and reduce of resources.WSN is also named as
MANET and contains a infrastructure less network structure. Every network contains some type of attack that affects the
network. One among these attacks is the selfish node attack that reduce the performance of MANET half the total
performance. To overcome this performance, new algorithm used to provide safe routing in the presence of selfish node
that not only prevents time needed to recover system from attack but also helps route the packet to destination fast.
