A mobile ad-hoc network is a self-configuring infrastructureless wireless network of mobile devices connected to each other. The major challenge in an ad-hoc network lies in adapting multicast communication to environments, where the mobility is unlimited and failures are frequent. Such problem increases the delay and decreases the throughput. In order to meet these challenges, this paper presents an algorithm to improve the performance of DSR protocol by using fuzzy logic in MANET. The data packets are served in FIFO order for packet schedulers in wireless adhoc networks. This paper presents a fuzzy based priority scheduler for MANET to determine the priority of the packet using DSR as a routing protocol. Network simulator 2.34 is used to check the performance. The scheduler is evaluated in terms of quantitative metrics such as packet delivery ratio, end to end delay and throughput. The main focus is on proposing a fuzzy approach to multi-packets scheduling in which the scheduling parameters are treated as fuzzy variables.
