Co-operative Radial-basis Neighborhood System for Distributed Mobility Management in Software Defined Mobile Networks

摘要

Software Defined Mobile Network enhances the user services based on network traffic, handoff latency, rate of call drops and packet re-transmissions. The principal components of Software Defined Network are configuration management, radio resource management, mobility management, network security and application services. This article proposes a Co-Operative Radial-basis Neighborhood (CORN) system for distributed mobility management in Software Defined Mobile Networks. CORN protocol creates a virtual layer of Mobile Host nodes to establish end-to-end connectivity in the network. Radial basis functions (neural network) are used to optimize the positions of mobile host nodes in CORN virtual layer. This approach reduces the control overhead, handoff latency and rate of packet loss in the network. Simulation results indicate that the proposed CORN protocol achieves an improved throughput rate with reduced latency as compared to the existing open-flow and software-defined virtual network techniques.
