Adaptive Fuzzy Route Lifetime for Wireless Ad-hoc Networks.

Ad-hoc On-Demand Distance Vector (AODV) routing protocol has been and continues to be a very active and fruitful research protocol since its introduction in the wireless ad-hoc networks. AO D V uses a static value fo r its route lifetime parameter called Active Route Timeout (ART) which states the time that the route can stay active in the routing table. Route lifetime may be more accurately determined dynamically via measurement, instead o f using a statically configured value. To accomplish this, the fuzzy logic system was used to obtain adaptive values fo r ART depending on the situation o f the transmitter and intermediate nodes. Analysis shows that the proposed design method is quite efficient and superior to the conventional design method with respect to data packet delivery ratio, routing overhead and average end-to-end delay.
