Simulationofa Load Balancing Routing Protocol<br />
Chapter 3<br />
To evaluate the packet delivery ratio and delay, all data packets generated at all<br />
nodes during the 3600s of simulation time were considered. Routing information<br />
packets were not considered. Packet delivery ratio is defined as the ratio of the<br />
number of packets received successfully by the intended destination to the number of<br />
packets that were generated. Delay was measured from the time the packet was<br />
generated to the time it was successfully received by the intended destination and<br />
includes the route request and reply phases, queuing at intermediate nodes and MAC<br />
interactions. Packets that did not arrive successfully at the intended destination were<br />
not considered for delay calculations. Simulation parameters are summarised in<br />
Table 3-1.<br />
