Abstract

Heterogeneity is a future generation network concept for Device-to-Device (D2D) communication. D2D communication commonly refers to a type of technology that enables devices to communicate directly with each other. Existing scheme of 5G network faces some challenges such as low decentralized mobility management, unified radio resource management, QoS mapping on radio links and coordination between access servers. To overcome those problems in the proposed EHSD framework we combine both Device-to-Device communication and handover mechanism in 5G heterogeneous network. The vertical handover mechanism is performed in Content Delivery Network (CDN) by applying fuzzy logic. Cramer-shoup KEM technique allows to provide security in user side. Additionally L7 switches and open flow controller are focused on load balancing, scheduling (Ant Colony Optimization) and routing (Ambience Awake) respectively. With our simulated and experimental results, outperforms the QoS parameters (bandwidth, throughput, signaling overhead and delay).
