| Abstract | Small cells such as femto cells are commonly being deployed for traffic offloading in heterogeneous wireless networks (HetNet), and multimode terminals designed for HetNets have the capability to simultaneously support two or more different classes of calls. A user having a multimode terminal with multiple ongoing calls that are connected through a femto cell may experience necessary handoff when the user moves outside the coverage area of the femto cell in a HetNet. However, the multiple handoff calls from the multimode terminal may be dropped because none of the available radio access technologies has enough residual capacity to accommodate the multiple handoff calls from the femto cells. In order to reduce the probability of dropping multiple handoff calls in HetNets, this paper proposes a handoff decision scheme that uses selective call dropping and bandwidth adaptation to decrease overall call dropping probability of multiple handoff calls. The proposed scheme uses individual call priority for performing selective call dropping. Performance of the proposed scheme is evaluated and compared for four different scenarios. Results show that the proposed scheme significantly reduces the probability of dropping essential handoff calls in HetNet. |

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.
