A dynamic overlay approach for mobility maintenance in personal communication networks - Springer

摘要

The location predictions of the nodes are the key issues in mobile environment. The applications like video sharing, voice over IP and other online applications offer better results with stable nodes. In mobile scenario, connectivity and quality of service are critical issues. To overcome these issues dynamic overlay approaches are proposed in this work namely, 1.Mobile Peers-Unstructured, 2.Structured Peer, 3.MANET Structure and 4.Mesh Backbone. These structures are obtained from the network, during the requirement of connectivity or quality of service. The performance of the proposed methods are analyzed in stable and mobile conditions by analyzing power consumption, hop stretch, packet delivery ratio, network life time and other QoS parameters.
