Research And Realization Of Ad Hoc Network Simulation Technology Based On Virtual-Reality Combination

Mobile Ad Hoc Network(MANET)network consists of several wireless mobile nodes with the capability of listening and discovering other adjacent nodes,without infrastructure or central management equipment.The network topology changes flexibly and automatically heals,and is widely used in disasters and environments without network facilities.The Ad Hoc network protocol based on cross-layer technology is one of the most widely used protocols.Compared with other Ad Hoc network protocols,it has the characteristics of improving network performance and stability.After theoretical analysis of the protocol,the performance of the protocol is generally verified and evaluated by simulation.However,the traditional simulation verification method lacks authenticity and real-time performance.In order to verify the performance of the Ad Hoc network protocol based on cross-layer technology with the participation of real elements,this paper studies and implements the Ad Hoc network simulation verification system based on the combination of virtual and real.To connect the real world,verify and evaluate the performance and applicability of the Ad Hoc network protocol based on cross-layer technology with the participation of real nodes,and realize the functions of data transmission and real-time communication between real and virtual.This system is necessary for verifying assumptions and implementing multi-layer protocols.Based on the OMNeT++ simulator,this paper designs and implements a network simulation verification environment combining virtual network and real nodes.This paper solves the problem of communication and interconnection between real elements and simulation network,and develops a virtual-real interaction interface.In order to solve the problem of lack of reality in traditional simulation,real data packets are captured and sent on the side of simulation verification environment.The simulation verification environment is also synchronized with the real time.In order to verify the performance of Ad Hoc network protocol based on cross-layer technology under the participation of real elements,this paper maps real nodes to virtual networks,and simulates,implements and verifies self-organizing network protocols through the interaction between real nodes and virtual networks.The design management module not only monitors and manages the simulation network,but also plays the role of monitoring real nodes.In order to verify the performance of the Ad Hoc network protocol based on cross-layer technology with the participation of real elements under the change of node topology,this paper changes the behavior of node clusters and changes the attributes of real and virtual nodes by issuing instructions.This paper verifies the time delay and throughput of the virtual-real interaction interface to support the communication requirements of the protocol,and tests the performance of real elements using the virtual-real interaction interface to send and receive high-speed services.
