Research On Resource Allocation Optimization Of Hybrid IoT Wireless Communication Based On WSN

With the continuous development of the Internet of Things,the scale of The Internet of Things based on wireless networks is becoming larger and larger,the functions are becoming more and more complex,and the Internet tasks are increasing as well.Due to the presence of a mobile node in the network,the tasks of the Internet resources requirements may change during the move of nodes.It may occur that the individual task needs much more resources in a short time.The power consumption of mobile nodes will increase with the enhancement of performance.In order to extend the life time,low power is also an important problem to consider.Therefore,how to achieve the balance of resources,power consumption and performance in large complicated wireless networks has become a new and urgent problem.The paper takes the analysis of the resources in the wireless network into priority,and then obtains the factors assigned to the wireless network resources.According to the precedence level of the elements and the weight of the corresponding elements,the concept of network communication performance management function is put forward,and the network communication performance index of the current task can be estimated according to this formula.In large complex networks,each network task establishes a task priority list in accordance with their network communication performance indexes.The higher index of the task priority list is,the quicker the system will execute.The paper analyzes the demand changes of the task in the network situation.According to the same elements of the corresponding level,we can establish priority table,and adjust the priority list on the basis of the size of each element weight.And then adjust the communication elements constantly through the target priority task to reach the goal.The operating system continues to run based on the new task priority list.In order to reduce the power consumption as much as possible in the configuration parameters,this paper has come up with a concept of power consumption index.In the process of resource allocation,the P-reasoning in the literature is used to judge the elements.The paper has studied and optimized aiming at the phenomenon of data collision.According to the scheme of resources allocation proposed in the paper,experiments are designed to verify the effectiveness and feasibility of that theory.Next,the paper design a WSN based on the Internet of Things system using the proposed resource allocation scheme,including the design of hardware module and the design of software.In order to be low power and energy saving,the paper has made a design and the effect has been verified by experiments.Finally,the resource allocation scheme is used in the actual project of the Wisdom Site,and just select one scene to analysis and make a comparison with the actual effect of the system operation.The result shows that the scheme can achieve the basic effect of resource allocation.
