Abstract
Conference Title: 2018 1st International Conference on Advanced Research in Engineering Sciences (ARES) Conference Start Date: 2018, June 15 Conference End Date: 2018, June 15 Conference Location: Dubai, United Arab Emirates The majority of contemporary 5G networks employ HetNets which improve data rate and the number of serving users over previous cell architecture. HetNets are comprised of different small-cell types such as femtocells and microcells. The tradeoff of these smaller cells is that they do not meet QoS requirements for flexibility and low latency because the increased frequency of handoffs increases network delay. This paper compares the state- of-the-art mobility management approaches that use SDN and (or) NFV concepts in 5G cellular networks. These approaches are evaluated in terms of scalability, signaling cost, probability of handoff failures, and system load balance.
