| Abstract | In IP mobility communications, handoff is one of critical points degrading mobile communications quality. To solve this problem, many network selection methods have been proposed. We also proposed a network selection method in handoff and multi-homing to improve IP mobility communications quality. To select the best network interface or communication medium, it is required to obtain QoS criteria such as transmission delay time and packet loss ratio. The mobile node itself may measure real-time network status to obtain the criteria, or the mobile node may obtain statistical information stored in any database on the Internet. Though the criteria collection way affects much on network selection, it is not discussed in detail in the existing research. The purpose of this paper is to consider the difference types of network selection criteria from the viewpoint of effects on IP mobility communications quality. For this purpose, we first designed and implemented two prototype systems to obtain the different types of the criteria. One is a function to measure real-time network status in a mobile node itself. The other one is to obtain the stored statistical information in the database on the Internet. Next, we compare the two kinds of criteria by some field experiments. For the experiments, we also implemented a prototype system using both functions in our proposed IP mobility architecture. Through the experimental evaluations, we showed quantitative comparison of two types of network selection criteria by satisfaction ratio of QoS required by some applications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
