The Research On Multi-interface Conversion And The Wireless Sensor Network Routing Algorithm

With the development of technology, the research on wireless sensornetwork technology is more and more extensive, the applications of wireless sensornetwork have been inextricably linked with our lives. Wireless sensor network iscomposed of a large number of stationary or mobile sensor which is consist ofself-organizing and multi-hop manner, these sensor put the information sent to thenetwork organization use ways of collaborate perception, acquisition, processing andtransmission of information which is perceived from area that coverage by thenetwork. Nowadays, wireless sensor network has been applied to the medical, homefurnishing, transportation, culture and other fields. Because of the energy of sensornode is not convenient to add, so make the data collection more efficient and energyconsumption more balanced has became the focus of current research.This paper mainly discussed interface conversion of sensor node and wirelesssensor network routing protocol algorithm. This paper firstly introduces thebackground and significance of the topic, the serial port and wireless sensor networkare summarized, then analysis and comparison of some typical routing protocol ofwireless sensor network algorithms, and then proposes an improvement scheme formulti interface conversion and a wireless sensor network routing protocol algorithm.The multi interface conversion studies the multi-serial conversion technology, whichcan simultaneous reception of multiple serial data, and then send the merged data inone serial. This design is using Verilog language above the FPGA, We have designedthe data receiver module, data transmission module, data cache module and frequencymodule, delay module, which can used to merge the data into one serial with no affecton the data rata. The feasibility of this design has been verified by the simulation onQuartus II and actual PC test. In the PC test,16groups of data with4800Hz baud ratacan be send with115200Hz baud rata with no affect, and the error data is0. Theadvantage of this design is saving the expenses of the hardware, and can use the serialeffectively, which is applied to current affairs monitoring of multiple data. This newtype of energy balancing algorithm for wireless sensor networks draws on the mainidea of the BCDCP routing protocol. When the base station divides the network, thenew algorithm makes the number of cluster heads equal to the optimal number ofcluster heads as far as possible. On cluster head election, not only the average energyof the sensor network, but also the remaining energy of the individual node must betaken into account. In data transmission, we use the multi-hop method to select theoptimal path. The simulation results show that the survival time of the network in thenew BCDCP-M algorithm is19%longer than BCDCP.In the end of this paper,multi interface conversion and NEW algorithm areapplied to the aquaculture environment monitoring system to test theirperformance.The results show, multi interface conversion can make multiple data fused into one high rata data timely and correct without change the rata oftransmission data; while the NEW routing algorithm in the system can extend lifetime113%and11.27%than LEACH and BCDCP.
