Research On Heterogeneity Between SDN Network And MANET Network

MANET network has the characteristics of self-organization,no center and multi hop.SDN has the characteristics of separation of control and forwarding and flexible management.It can well solve many problems faced by many traditional networks.At the same time,SDN technology can reduce the burden of data network.Therefore,SDN technology is now widely used in various fields such as traffic engineering,network security,network management and so on.This thesis presents several heterogeneous schemes of SDN network and MANET network,as well as the exception handling scheme for heterogeneous networks.The main research contents are mainly reflected through three experiments:In a specific scenario,SDN network and MANET network are heterogeneous.The experiment shows that SDN network and MANET network are heterogeneous and have certain advantages over traditional network and MANET network.In the case of SDN network failure,SDN network will degenerate into IP network in a short time.IP network can communicate with MANET network normally.The degradation process is realized through vertical switching of heterogeneous networks.This thesis proposes an improvement of network heterogeneous mode,adds SDN technology to the MANET network,and takes SDN control group as the representative of SDN network.Through this mode,SDN network and MANET network form a heterogeneous network,mainly in order to improve the overall performance of MANET network,and designs an experiment to verify the heterogeneous network composed of SDN network and MANET network.Finally,SDN technology is used to realize the automatic vertical handoff of heterogeneous network protocols.The experimental simulation supports multiple network protocols in a network.The design scheme is designed to simulate the vertical handoff of network protocols,and SDN is used to control the automatic vertical handoff of heterogeneous networks.Experiments show that SDN technology can be applied to the vertical handoff of heterogeneous networks including MANET networks,and can achieve effective results.The innovation is that multiple schemes realize the heterogeneous network composed of SDN network and MANET network,and prove the feasibility and advantages of the heterogeneous network.Not only that,SDN technology can also be applied to network detection and control other heterogeneous networks for vertical switching.Experiments verify the realization of the corresponding functions.
