Abstract


Multi- sensor network integrated sensor technology , embedded computing technology , MEMS technology and wireless communication technology , is composed of a large number of sensor nodes deployed in the area of monitoring , can collaborate to complete real-time monitoring , sensing and acquisition target object , and it is processed and transmitted to the need for the user of the information . Multi-sensor networks as one of the emerging technologies in the future , its development and wide application , people's social life and industrial change will bring great impact . Perception , processing and communication capabilities of the sensor nodes are very limited , and therefore need to work together to accomplish tasks between multiple sensor nodes . The coverage problem is a main part of the cooperative control is also the focus of this discussion , mainly to solve the sensor nodes are randomly deployed to the monitoring area , take the node deployment algorithm to ensure that the region can be effective monitoring of the sensor nodes , minimizing inter-node traffic , thus prolonging the survival time of the network . Multi- sensor network coverage control problem in-depth study by the theoretical analysis , geometry proof way to get a sensor node deployment method based on an equilateral triangle network coverage , be able to achieve monitoring area with the least amount of sensor nodes completely The sewn coverage . On this basis to obtain the zone k heavy coverage and local k variable coverage sensor node deployment algorithm can achieve weight seamless coverage and local region of the surveillance area k k variably covering . Algorithm node arrives at the destination vertex moves the shortest distance from the effective node energy savings , lower energy consumption and prolong the survival time of the entire network . Finally, the algorithm in MATLAB 7.0 environment simulation experiments , the results show that the algorithm can achieve effective coverage of the monitoring area .
