ABSTRACT
Quality of Service (QoS) is a tool to measure the efficiency of the Ad-hoc network. QoS is a complex function because it depends mainly on four factors (throughput, packet delivery ratio, end-to-end delay and jitter). These four factors are functions of internal factors and are variables with the time. In the result the QoS is an ambiguous tool. This paper proposes a brand-new method to solve this ambiguity, it will use the fuzzy technique to simplify the QoS factor and summarize it in a simple form or in a single value for each application. So it will summarize all factors of the QoS in a single value for the network if the applications share is defined. This paper will apply the propose method on Mobile Ad-hoc NETwork (MANET) with different protocols. The new algorithm will summarize the efficiency of each protocol in a single (crisp) value for all applications. Finally, an important conclusion is proved, by experimental result, implying that higher throughput does not usually mean high QoS supported by the protocols.
