ABSTRACT:
Mobile Ad Hoc Network
(MANET) is a reliable system formed by co-operating and independent nodes that
connect and communicate with each other wirelessly without pre-existing
infrastructure. In such a network, the easiest way to broadcast the packets to
all network nodes is flooding. However, flooding leads to serious drawbacks
such as collision, contention and redundant retransmission. These drawbacks are known as the broadcast storm problem. This
research proposes an adaptive algorithm in order to decrease the overall
network overhead and minimize the problems associated to flooding. Moreover
this research concentrates on studying the effect of using different mobility
models that provide general idea about nodes movement, status and locations. In
particular the performance of Random Waypoint and File mobility models in terms of their effect on network
communication is evaluated. Moreover, this research provides performance
evaluation of different traffic types such as Constant Bit Rate (CBR) and
Traffic GEN. Results from Qualnet simulations have revealed that the new
proposed algorithm outperforms flooding in terms of different metrics: reducing
end-to-end delay in addition to minimizing the normalized routing load and
maximizing the packets delivery ratio, in addition to concluding that Traffic GEN outperforms the CBR in terms of throughput. Moreover
the CBR traffic has higher delay values than Traffic GEN.
