Sensor network plays an important role to retrieve environmental information for IoT (Internet of Things). To minimize deployment cost of large scale indoor sensor networks, we are developing ZigLoc, a sensor localization system that requires no anchor deployment. In ZigLoc, sensor location is estimated using WiFi fingerprints, which are collected for a WiFi localization system. This paper brie...

Deployment of sensors is the primary task in sensor networks, in large part, it is in relation to the network running status and life, and it also has a great impact on feasibility of optimization calculation. And coverage controlling is the first consideration that people should consider when deploy wireless sensor network nodes for it affects the performance of wireless sensor network (WSN) i...

Wireless sensor networks are presently a growing area as they form a platform for many applications associated to surroundings monitoring, fitness and wellbeing, supervision and military surveillance. One of the major design aspects of Wireless Sensor Network (WSN) is the sensor node deployment strategy. The deployment strategy is vital because it can affect the performance of the network. A Gr...

Further research has been done in order to reduce the energy consumption of the mine roadway wireless sensor nodes and prolong the lifetime of the network. On the basis of analysis and study on the existing linear wireless sensor network nodes deployment, the node distance optimization deployment scheme with sinks in the center is proposed. The calculation method for optimized distance between ...

For node deployment of heterogeneous sensor networks, based on different probability sensing models of heterogeneous nodes and an organic small molecule model, a ‘class-molecule’ sensing model of heterogeneous nodes is proposed. Combining it with DSmT data fusion model, the change of network coverage ratio after using the new sensing model and data fusion algorithm is studied. Furthermore, acco...

Coverage pattern and deployment strategy are directly related to the optimum allocation of limited resources for wireless sensor networks, such as energy of nodes, communication bandwidth, and computing power, and quality improvement is largely determined by these for wireless sensor networks. A three-dimensional coverage pattern and deployment scheme are proposed in this paper. Firstly, by ana...

With recent advances in electronics and wireless communication technologies, the Wireless Sensor Networks (WSNs) are being used in wide range of applications of military, ecological, health related areas. Due to their resource constraints such as, sensor node’s size, memory, and processing capabilities, the scale of deployment of WSNs requires careful decisions with respect to various performan...
