Abstract

A wireless Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration, in which all nodes potentially contribute to the routing process.

In this paper, we analyze packet scheduling algorithm to find those that most improve performance in congested network. Hence, a scheduling algorithm to schedule the packet based on their priorities will improve the performance of the network. Packet schedulers in wireless ad hoc networks serve data packets in FIFO order. Here, we present a fuzzy based priority scheduler for mobile ad-hoc networks, to determine the priority of the packets using Destination Sequenced Distance Vector (DSRs) as the routing protocols. The performance of this scheduler has been studied using OPNET simulator and measured such as packet delivery ratio, end-to-end delay and throughput. It is found that the scheduler provides overall improvement in the performance of the system when evaluated under different load and mobility conditions.
