In our day-to-day life, wireless technology plays a great role, because users move from place to place across the globe, it’s important to think about the type of network we can deploy quickly. Collection of two or more node forms A mobile ad-hoc network (MANET) without the aid of any centralized infrastructure. There are independent nodes that communicate without a wire in a mobile ad hoc network. Due to the behavior of nodes in MANET the time when node joining/leaving the network is unknown. This study focuses on improve performance of DSR protocol affected due to selfish nodes. So, identify path without any selfish node is the main issue for delivering a packet by selecting a reserved path. The algorithm counts the number of failed route request messages to aware the selfish node that causes failure on NS-2 simulator tools. The node is assigned to indicating the selfishness status of the node during route discovery. In this study the researcher conducts performance evaluation of existing DSR and modified one is assessed by using packet delivery ratio, and endto-end delay metrics and achieved very good result.
