ABSTRACT: Network
Coding is a relatively new forwarding paradigm where intermediate nodes perform
a store, code, and forward operation on incoming packets. Traditional
forwarding approaches, which employed a store and forward operation, have not
been able to approach the limit of the max-flow min-cut throughput wherein
sources transmitting information over bottleneck links have to compete for
access to these links. With Network Coding, multiple sources are now able to
transmit packets over bottleneck links simultaneously, achieving
the max-flow min-cut through-put and increasing network capacity. While the majority of
the contemporary literature has focused on the performance of Network Coding
from a capacity perspective, the aim of this research has taken a new direction
focusing on two Quality of Service metrics, e.g., Packet Delivery Ratio (PDR)
and Latency, in conjunction with Network Coding protocols in Mobile Ad Hoc Networks (MANETs). Simulations
are performed on static and mobile environments to determine a Quality of
Service baseline comparison between Network Coding protocols and traditional ad hoc routing protocols. The results
show that the Random Linear Network Coding protocol has the lowest Latency and Dynamic
Source Routing protocol has the highest PDR in the static scenarios, and show
that the Random Linear Network Coding protocol has the best cumulative
performance for both PDR and Latency in the mobile scenarios.
