A Trusted MANET Routing Algorithm Based on Fuzzy Logic

Abstract MANET wireless network changes network topology continuously and dynamically due to the absence of infrastructure and central control. Typically, this network used for areas where unavailable basic communications services such as battlefield, emergency relief, and virtual classes. However, ad hoc networks exposed to different attacks as in malicious or selfish nodes that impede packets delivery. A new algorithm proposed of the MANET using a fuzzy logic system to solve malicious nodes problem. The routing algorithm relies on two main principles as trust level and shortest path (hops count). The finding obtained from three key parameters as high packet delivery fraction with low end-to-end delay and normalized routing load in this study. These results calculated based on the comparison between the FLTS algorithm with AODV protocol and without a drop.
