S. Malathy, G. Sudha Sadhasivam, K. Murugan, S. Lokesh

TL;DR
This paper proposes a new admission control policy for cellular networks that effectively reduces call dropping and handoff failure probabilities while maintaining low blocking rates for new calls.
Contribution
It introduces a novel admission control policy that manages bandwidth sharing and slot allocation to improve QoS during handoffs in mobile networks.
Findings
Handoff dropping probability is minimized.
Call dropping probability is also reduced.
Low blocking rates for new calls are maintained.
Abstract
Mobility management and bandwidth management are two major research issues in a cellular mobile network. Mobility management consists of two basic components: location management and handoff management. To Provide QoS to the users Handoff is a key element in wireless cellular networks. It is often initiated either by crossing a cell boundary or by deterioration in the quality of signal in the current channel. In this paper, a new admission control policy for cellular mobile network is being proposed. Two important QoS parameter in cellular networks are Call Dropping Probability (CDP) and Handoff Dropping Probability (HDP). CDP represents the probability that a call is dropped due to a handoff failure. HDP represents the probability of a handoff failure due to insufficient available resources in the target cell. Most of the algorithms try to limit the HDP to some target maximum but not…
