In the process of the wireless sensor network research, the issue on the energy consumption and coverage is an essential and critical one. According to the characteristic of the sensor nodes, it is homogeneous, and we proposed the k-degree coverage algorithm based on optimization nodes deployment. First, the algorithm gives the solving procedure of the maximum seamless coverage ratio, when the three-node joint coverage has been provided. Second, when the sensor nodes are covering the monitoring area, the algorithm gives the solving procedure of the expected coverage quality and the judgment methods of the coverage ratio, when the nodes are compared with the nearby ones. And when there is redundancy coverage in the given monitoring area, we have given the solving procedure of any sensor nodes that exist in the redundant nodes coverage. Finally, using the simulation experiment, the results of the coverage algorithm based on optimization nodes deployment are compared with other algorithms in terms of the coverage quality and the network lifetime, the performance indexes have enhanced to 13.36% and 12.92% on average. Thus, the effectiveness and viability of the coverage algorithm based on optimization nodes deployment have been proved.

Some approaches and strategies of building a manufacturing process managing system in a digital enterprise environment were introduced in this paper. The system was based on resource optimization deployment and composed of five subsystems. Firstly, the structure of the whole system's framework and the function of every subsystem were discussed. Then the XML-based data exchange between different subsystems, data access interface specification, and the integration pattern based on XML Web Services were presented in detail. Finally, a successful enterprise application of the system was described. The application result proves that the system was practical and helpful to achieve the order-oriented manufacturing process collaborative management and the social manufacturing resources' optimization deployment.

Aimed at the electromagnetic compatibility problems between same frequency radars on fleet battle ships, the maximum radar range is used to describe the EMC degree between the same frequency or similar frequency radars in radar system. The radar system is divided into Omani-directional antenna and directional antenna radar to analysis and get the two radar electromagnetic compatibility models, then the EMC degree model of entire radar system. Quantitative analysis of the simulation is represented for the relationship between several important parameters and EMC degree. It is an important complement of the radar deploymentoptimization methods, which provides a digital basis for analyzing the radars maximum benefit when coordinating combat.
