IV SIMULATION SETUP
The analysis and comparison of protocols can be evaluated by real world experiments or simulation. Since simulation is cheaper or flexible more research work of wireless sensor network s conducted using simulation software. It reduces the need for time consuming and costly real world experiments. The simulation used in my analysis is Network Simulator-3. The reason for choosing this software is live visualizer, connected to real world, portability.
The main aim of this paper is to compare the performance of AODV, DSDV, OLSR and DSR in different simulation environments. The comparison was made by varying the node density and the simulation environment one at a time and keeping all the nodes as constant…show more content… The main objective of this paper is to extend the lifetime of the sensor nodes in a network. The protocol offers some suitable alternate routes for packet forwarding in presence of node or link failure in the current route. The protocol takes care of energy efficiency an reliability of a routes. A.PERFORMANCE METRICS
The required parameters to analyse a four routing protocols AODV, DSDV, DSR and OLSR are: AVERAGE END TO END DELAY
Average time delay for send data packet from the source node to destination. When average delay is less, then the performance is better.
THROUGHPUT
It is the ratio between the actual number of packets transmitted by the nodes in the system to the number of successfully delivered packets at the base station. Higher throughput is desirable.
JITTER
It is the variation in delay by different data packets that reached the destination. Smaller jitter should make performance better.
