A Research And Implementation Of Wireless Sensing Data Transfer Protocol For Outdoor Warning

Wireless sensor networks(WSNs)have potential in many applications,such as military targets tracking and monitoring,natural disaster relief,biomedical health monitoring,dangerous environmental exploration,and earthquake awareness.This article studies a wireless sensor data transfer protocol(WSDTP)applied to wireless sensor networks for outdoor early warning,including the study of the agreement protocol identification technology,alert mobile phone running state conversion technology and the role conversion technology of alert mobile phone,and providing necessary sensor data transmission and mobile phone state switching technology for outdoor workers' early warning system in night camping.The main work is summarized as follows:1.Analyze and summarize the research status of the existing sensor data transfer protocol,and point out the shortcomings of a project in data transmission ability.2.This study introduces the sensor data transfer mechanism,alert mobile phone running state transition mechanism and alert mobile phone character conversion mechanism.On this basis,establish the pushdown machine on the sensor data transfer mechanism,alert mobile phone operating state transition mechanism and alert mobile phone role conversion mechanism,and then provide formal verification to the final state of access of the three mechanism.According to this process design the protocol body,protocol message and protocol logic for the protocols of sensor data transmission,alert mobile phone operation state transition and alert mobile phone character conversion protocol,on which the algorithm flow diagram and the algorithm pseudo-code of each protocol are given;in the end,give out the solution of sensor data transfer protocol through the above key technologies.3.According to the given solution,based on object-oriented software development methods,design multicast data transmission,alert mobile phone running state transition,case,sequence and class diagrams of the role transition of alert mobile phone.On this basis,encode and implement wireless sensor data transmission protocol for outdoor early warning according to the protocol message and the static operation of the message given by the class diagram.4.Follow the project requirements,design test cases,verify multicast data transmission,and alert mobile phoneopretating state transition and role conversion function of the wireless sensor data transmission protocol.Experimental results show that,this paper's studies of the WSDTP protocol,its multicast data transmission function,alert the phone's running state transition function and alert mobile phone's role conversion function have reached the requirements of verification.5.Results of the comparative analysis with 10 related protocols including CMRP,VCHEC,DHCP and MHCOA show that:WSDTP studied in this thesis has the same capacity with SNOMC,reaching 0.6 in the aspects of functional setting and performance,but lacks actual deployment and requires wireless AP infrastructure support for deployment.Therefore,it is necessary to strengthen the field deployment and to minimize the denpendency on infrastructure,to facilitate better service in outdoor operations.Second,in the alert mobile phone running state transition,the given running state transition sub-protocol uses three messages.Although the conversion efficiency is low,the protocol expresses with high accuracy.Protocol with higher accuracy,i.e.,the WSDTP studied in this thesis is needed,in relatively poor outdoor operating environment.Last,in the alert mobile phone transition,the WSDTP studied in this thesis reached a balance between the effectiveness and semantic satisfaction of the protocol,but the effectiveness needs further improvement,that is,further streamline the number of messages.
