Partition based Mobility Management Technique ( PMMT ) in MANET for better QoS

The mobility in mobile ad hoc networks is an application that uses location information of nodes in a network to identify present location of a node. Since we need to get better QOS, mobility management is considered scalable and dynamic compared to other QoS parameters in mobile ad hoc networks. Mobility management in mobile ad hoc networks are mainly motivated by the adoption of dynamic mobility of nodes due to scalability issues. However, mobility management is difficult when there is highly dynamic and frequent changes in the topology may be hard to predict and nodes are mobile or frequently disconnected to save battery power. Therefore, In this paper, we present a novel mobility management mechanism called PMMT: Partition based mobility management technique. In PMMT, the entire network is partitioned into a regions of smaller and smaller regions. For each node, at each level, once node belongs to particular region-level of the hierarchy and is chosen as its location for location information server and and periodically updates them with its location. The main contributions of the paper are: First, we present a node mobility mechanism based on partition. Second, we present a mechanism for location server mobility.
