Mobility based Cross Layer Optimization with QoS for HetNets

QoS NSIS Signaling Layer Protocol for Mobility Support with a Cross-Layer Approach

Providing seamless QoS guarantees for multimedia services is one of the most critical requirements in the mobile Internet. However, the effects of host mobility make it difficult to provide such services. The next steps in signaling (NSIS) was proposed by the IETF as a new signaling protocol, but it fails to address some mobility issues. This paper proposes a new QoS NSIS signaling layer protoc...

1 Mobility performance optimization for 3GPP LTE HetNets

Heterogeneous networks (HetNets) are being deployed as a feasible and cost-effective solution to address the recent data explosion caused by smart phones and tablets. In a co-channel HetNet deployment, several low-power small cells are overlaid on the same carrier as the existing macro network. While this is the most spectrally efficient approach, coverage areas of the small cells can be signif...

HWN* Mobility Management Considering QoS, Optimisation and Cross Layer Issues

In this paper, we address mobility management for 4th generation heterogeneous networks from a quality of service (QoS), optimisation and cross layer design perspective. Users are classified as high profile, normal profile and low profile according to their differentiated service requirements. Congestion avoidance control and adaptive handover mechanisms are implemented for efficient cooperatio...

Cross-Layer Authentication Protocol Design for Ultra-Dense 5G HetNets

Creating a secure environment for communications is becoming a significantly challenging task in 5G Heterogeneous Networks (HetNets) given the stringent latency and high capacity requirements of 5G networks. This is particularly factual knowing that the infrastructure tends to be highly diversified especially with the continuous deployment of small cells. In fact, frequent handovers in these ce...
