Abstract
Correct operation of MANET needs mutual cooperation of collaborating nodes. as a result of presence of stingy or malicious nodes, performance of network degrades considerably. stingy nodes drop packets coming back from its neighbor nodes to conserve its energy or speed their own packets within the buffer queue. to stop this wrongdoing, stingy nodes have to be compelled to be detected and isolated from network. This paper, notice stingy nodes that ar created as a result of nodes preserving their energy. when their detection, performance analysis of networks has been done by scrutiny the perfect network and therefore the network with stingy node victimization NS2.
