Abstract

The invention discloses an IP-based software defined ubiquitous wireless MANET routing architecture, the wireless MANET routing architecture comprises three basic layers: an application plane, a control plane and a data plane, and the application plane comprises routing, data application, security, load balancing, strategy, QoS and the like, wherein the control plane comprises a control plane of amobile SDN controller MSC and a control plane of a mobile node (MN), the control plane of the mobile SDN controller MSC comprises a connection management module, a topology learning module, a forwarding management module and OpenFlow message compression and decompression, and the control plane of the mobile node MN comprises an OpenFlow message compression and decompression local adaptive controller LAC and a flow table FT, the data plane has the functions of forwarding an entered media stream according to a flow table FT rule and compressing / decompressing a packet header. According to the MANET routing system structure, position service support for tracking node positions is not needed, the size of Openflow messages is reduced through a compression and decompression method, and air interface resources of nodes are saved.

Description

Technical field [0001] The invention relates to the technical field of computer networks, in particular to an IP-based software-defined ubiquitous wireless MANET routing system structure. Background technique [0002] Delyet et al. proposed a wireless Mesh network architecture that uses devices that support OpenFlow as the access point and gateway. The SDN controller triggers and manages the switching of mobile nodes (MobileNode, MN) between access points (AP), and uses the optimized link state routing protocol (Optimized Link State Routing, OLSR) protocol for multi-hop routing. De Gante et al. proposed a wireless sensor network (WSN) architecture in which the SDN controller, as part of a fixed base station, has a direct control link to the sensor node. The SDN controller uses location services to collect node location information to learn network topology. Location services are used to select network routes and update sensor node flow tables (FlowTable, FT). Wang et al. propos...
