Analysis of Fuzzy Logic Usage in PBHRA Routing Algorithm in Wireless Ad Hoc Networks

Mobile ad hoc networks are composed of nodes communicating with each other without any infrastructure. Position based routing algorithms used in these networks makes the decision of routing by considering the location information of wireless nodes. In this study, the effect of using fuzzy logic during the decision making about routing of nodes that are using one of the location information based algorithm PBHRA (Position Based Hybrid Routing Algorithm) in the literature has been examined. 50-noded and 100-noded networks that are using PBHRA have been subjected to routing operation with and without using fuzzy logic. The results have been given relatively. It is shown that the usage of fuzzy logic provides the effective usage of band width and battery life, which are counted as the constraints of ad hoc networks.
