Analysis of Dynamic Overlay Architecture for the Quality of Experience (QoE) Improvement in Wireless Networks

摘要

Wireless network has different architectures based on the structure of the network. In the proposed overlay architecture, the better communication is achieved by combining the different networks. The specific service overlay network is focusing mainly on the delivery path. This existing technique considers the management node to monitor the network for getting the quality of data transmission. Due to the management node, it has high complexity and delay. Another existing technique is overlay information centric network (OICN) which focus on reducing the cost and node deployment. The OICN technique separates the data plane and control plane, based on the control plane information, data plane will be activated. This existing technique produces delay and high packet loss due to fault information from control plane. To overcome all the above issue, a new technique is generated which is called as overlay approach in different architecture (OADA). This proposed OADA technique consists of four different architectures such as distributed, centralized, hybrid and clustered architecture. Peer to peer distributed architecture act as server nodes and the remaining architectures act as client nodes. Centralized architecture reduces the security issues, hybrid architecture increases the scalability and reliability and clustered architecture improves the network performance. Experimental results analyze the different architectures using the QoS parameters for QoE.
