Ad-hoc network is an infrastructure less wireless network. Ad-hoc networks do not have a constant topology due to mobility of the nodes. The nodes keep a track of this dynamic topology by announcing its presence through broadcasting and listens to the presence of other nodes. Each node maintains the table of information regarding the topology. There many protocols such as AODV, DSR and FSR. These protocols maintain the topology information in different ways. This paper focuses on analyzing the performance of the protocols based on some quality of service parameters such as packets lost, end to end packet delivery delay, and jitter and packet delivery ratio.
