Mobility Management using Fuzzy-Logic based DQS in MANETs

摘要

Mobile Ad-Hoc network (MANET) is the network of mobile nodes which has no fixed infrastructure, and mobile node in MANETs can roam and communicate freely. Recently, many researches for mobility management of mobile nodes are actively carried out by using location information of mobile nodes. The mobility management is an important issue in MANETs because location information of mobile nodes is frequently changed and it can aggravate the performance of MANETs severely. In this paper, we propose a mobility management method using fuzzy-logic based Diamond Quorum System (DQS) by considering the mobile nodes' locality in order to manage location information of mobile nodes in MANETs efficiently. The proposed scheme selects mobility databases adoptively from DQS by considering the gravity of locality of a mobile node. The performance of the proposed scheme is evaluated by an analytical model and compared with those of existing UQS based mobility management scheme.
