Mobility management challenges and issues in 4G heterogeneous networks

ABSTRACT

Mobility is one of the most invigorating features, having an enormous impact on how communication is evolving into the future. Mobility in 4G networks requires new level of mobility support as compared to traditional mobility. There is plenty of related research on mobility in next generation networks, which promises support for emerging ambient and ubiquitous communications. This paper aims to identify and explore the different issues and challenges related to mobility management in 4G heterogeneous networks. A review of the existing solutions and ongoing projects related to these mobility management issues is presented; which can help in discovering a unified approach to seamless mobility in future generation networks.
