Performance of DNS as Location Manager using Random Waypoint Model

— Domain Name System (DNS) can be deployed in the network as a Location Manager (LM) for mobility management. The suitability of DNS as a LM can be measured on how successfully it can serve to locate a mobile host. In this paper, we developed an analytical model to measure the performance of DNS as LM for mobility management techniques with IP Diversity support based on success rate which takes into account the Radius of the subnet, the residence time of MH in that subnet, latency in the network and the overlapping distance of two neighboring subnets. Our analysis shows that for a reasonable overlapping distance, DNS can serve as a LM with very high success rate even under some high network latency.
