An Adaptive Location Service on The Basis of Diamond Quorum for MANETs

Mobile ad-hoc network (MANET) is a network of mobile nodes that do not have a fixed infrastructure. Recent research in this field addresses ways of solving existing problems in a MANET by using the node location information. However, maintaining the location information of the nodes is one of the essential challenges in mobile ad-hoc networks because the location of a node changes frequently. In this paper, we propose an adaptive location service on the basis of diamond quorum system (DQS) considering the gravity of locality that is managing the location information for all nodes efficiently in a MANET. In a proposed scheme, the mobility database storing the location information of a mobile node can be selected adoptively from the DQS by considering the gravity of locality. The performance of a proposed scheme is to be evaluated by an analytical model, and compared with that of existing uniform quorum system (UQS) based mobility management scheme.
