The Design And Implementation Of A Clustering Routing Protocol For WSN Based On IEEE 802.15.4

Research on reducing energy consumption in wireless sensor network(WSN) involving various critical technologies,develop an energy efficient routing protocol is one of the critical technologies.WSN routing protocol provide reliable data transmission for sensor node.In the process of design,the design scheme is conditioned by demand from actual scene.This paper has deeply researched WSN routing protocol,designed a clustering routing protocol based on IEEE 82.15.4 for indoor positioning systems.The network layer functions include converger channel selection, father node address allocation, node's in of the network routing choice, establishment and maintenance of neighbor table and data transmission fault-tolerant mechanism.This paper presents a routing protocol against path optimization problem for WSN based on improved shuffled frog leaping algorithm(SFLA).The SFLA was used as wireless sensor network path optimization main frame, gauss mutation and opposition-based learning were used to overcome the defects of easily trapping into local optimum and low accuracy computation.The core part of sensor node hardware is composed of CC2530 micro-controller and CC2592 radio frequency front-end.The maximum power output of theoretical value is 22 dBm completely satisfy the requirement of the system.Software realization based on TI-MAC protocol stack and easy to transplant.Test results show that this thesis design of the clustering routing protocol for WSN provides steady and responsible real time data transmission and meets the need of indoor positioning system.The optimizing strategy based on improved SFLA can prolong the life of network and then improve the energy efficiency.
