Research And Implementation Of Smart Networking Technology In Ad Hoc Network

As an important development direction of modern mobile communication,mobile Ad Hoc network,based on its characteristics of self-organization,no center and no base station,can flexibly and quickly build its own network in the case of unpreset basic communication equipment or equipment damaged,and has broad development prospects in many fields such as military rescue.Based on OMNeT++,this paper designed and implemented the simulation test platform of mobile Ad Hoc network smart network,added the interface of real-time interaction with external programs in the simulation network,and realized the smart network management of network simulation module during the simulation running by connection control software.Physical layer parameters and movement parameters of the nodes in the simulation can be configured smartly in real time by transmitting link quality report and node trajectory information,and networking clustering and data transmission of the network in the simulation can be controlled smartly in real time by delivering service instructions.In this paper,based on the practical application design mobile Ad Hoc network nodes in smart network simulation test platform of application layer model,in view of the node net clustering,in clusters,a new cluster,withdrew from the network,such as cluster management and data transmission business scenarios to perfect the function of the application layer,external was achieved by the application layer in the simulation network instruction,complete smart network control,regulate the overall operation of the network.At the same time,due to the limited resources of a single node in Ad Hoc network,this paper according to the node location,connectivity,moving speed,relative moving speed and other parameters design the cluster maintenance algorithm of the smart networking simulation test platform.Cluster head node runs the algorithm to update the optimal cluster head in time and maintain the stability of network cluster structure.The smart network simulation test platform can operate the network after the simulation starts.The simulation scenarios that can be tested are diverse,and the complex and changeable network operating environment and node state fluctuation can be simulated to ensure the authenticity and reliability of the simulation results.In addition,due to meet the requirements of delivering tasks during the simulation,select some nodes to form temporary task subnets to execute tasks.This paper designs a subnet formation algorithm for Ad Hoc network based on task location,task intensity,task priority,node location,node connectivity,node identity,node moving speed,node relative moving speed,node remaining energy and other parameters.After receiving the instruction,the ground node selects some nodes to perform the task and form a temporary subnet by using the subnet formation algorithm.After the task is completed,the subnet is dismissed and the node is re-connected to the network to fulfill the service needs.The algorithm is simulated and verified on the smart network simulation test platform,and the performance of the algorithm is compared with other algorithms,which proves that the network performance is excellent.
