Design And Implementation Of Real-time Routing In The Wireless Sensor Network

In the wireless sensor network, the real-time applications gradually increase. If thenetwork design cannot meet the real-time requirement of the application, the systemsatisfaction of users using the application will be affected inevitably, which will bring ahuge loss to the system operator. So how to satisfy the real-time demand of real-timeapplications in the wireless sensor network is crucial. In recent years, the rapiddevelopment of wireless communication technology provides technical basis for thereal-time transmission method of the node in gathering information. This paper mainlyresearch on the real-time routing strategy in the wireless sensor network and solve theproblem that how to ensure the data real-time transmission in the fire rescue site. Thispaper mainly completed the following work:(1)The current routing methods in the wireless sensor network are invested. Bycomparing the structure differences of the clustering network and non clusteringnetwork and the applicable scope of real-time routing and non real-time routing in theabove two kinds of networks, the research direction of the topic is determined as thereal-time routing strategy research and design in clustering network for thecharacteristics of real-time service.(2)A real-time routing strategy in the wireless sensor network is designed. In theuneven cluster network model, we respectively design the information forwardingmethod for cluster nodes and head node, and improve the information deadline storagemethod of the above two methods. Through simulation, the routing strategy proposed bythis topic and the existing ones are compared, the performance of routing strategyproposed in this paper is verified.(3)The analysis and design of real-time routing strategy in the fire rescue scenario.Firstly, we analyze the scale of fire-fighting robots and the demand of real-time routingfor the fire information in the fire rescue scenario; secondly, for the above analysisresults, the fire-fighting robots network model in the fire rescue scene is analyzed anddesigned; Thirdly, the forwarding methods of the gathered information by the clusterrobot and the cluster head robot are designed.(4)Simulating the information transmission process that fire-fighting robots collectfire information in the fire rescue scenario. In order to take more visually observation on the data transmission process, we design each module hardware circuit and the systemhardware circuit that can be applied to the sensor nodes of the fire-fighting robots aswell as each module program and the overall program, and use the physical design ofthe hardware node to simulate the cluster nodes real-time transmission process ofgathering information as well as the cluster head one.
