Mobility Management Using Fuzzy-Logic Based 4-Group Quorum System in MANET
نویسنده
چکیده
Mobile Ad-Hoc network (MANET) is the network of mobile nodes, which has no fixed infrastructure, and mobile nodes can roam and communicate freely each other. Recently, many researches for mobility management are carried out actively by using location information of nodes. The mobility management is an important issue in MANET because location information of mobile nodes is frequently changed and it aggravates the performance in MANET severely. In this paper, we propose a mobility management method using fuzzy-logic based 4-group quorum system (GQS) by considering the mobile nodes' locality in order to manage location information of mobile nodes in MANET efficiently. The proposed scheme selects mobility databases adaptively from 4-GQS by considering the locality of a mobile node. The performance of the proposed scheme is evaluated by an analytical model and compared with that of existing Uniform Quorum System (UQS) based mobility management scheme.

Mobile Ad Hoc Network (MANET) is a mobile distributed wireless networks. In MANET each node are self capable that support routing functionality in an ad hoc scenario, forwarding of data or exchange of topology information using wireless communications. These characteristic specifies a better scalability of network. But this advantage leads to the scope of security compromising. One of the easy ...

As a kind of typical embedded system, MANET is a multi-hop self-configuring network with the topology changes dynamically. To model of the security, mobility, and dynamic changes of MANET, trust is used as a novel concept recently. In this paper, based on the classic fuzzy theory, the trust evaluation and the dynamic routing protocols for MANET are represented, to give the modeling of MANET wit...
