Introduction:
Performance is a key criterion in the design and use of com-
puter systems.The main goal of Computer system engineers,scientists,analysts
and users is to get the highest performance for a given cost.To achieve that
goal a basic knowledge of performance evaluation terminology and tech-
niques.
Performance Evaluation:
Performance evaluation is an art. Selecting
an evaluation technique and selecting a metric are two key steps in all per-
formance evaluation projects.
System:
Mobile ad hoc networks (MANETs) consist of mobile wireless
nodes connected in such a manner so that the communication between nodes
is carried out without any centralized control. MANETs are self-organized
and self-congurable network where mobile nodes move arbitrarily. Routing
is a crucial issue in MANETs. Therefore, emphasis is to evaluate the perfor-
mance of three routing protocols DSDV, DSR and AODV for Constatnt Bit
Rate (CBR) trac by varying network scope i.e. number of participating
nodes. The parameters used for evaluation are packet delivery ratio(PDR),
end to end delay(Delay), routing overhead and throughput. The simulations
are carried out using Network Simulator NS2
