For the high cost of deployment and maintenance of existing device in the explosive production, it is necessary to establish the digital managing system to real-time transmit the information of producing. So the monitoring system of explosive production based on the Internet of Things (IoT) technology is designed. The self-adaptive network is the key of the managing system of explosive production,...
A constraint-based sensor network nodes particle swarm search localization algorithm (CPL) is presented. First of all, a constraint domain of an unknown node must be determined; Then the positions which meet specific criteria is searched out by particle swarm optimization algorithm and the searching results within the constraint domain are recorded; Finally, the unknown node's localization can be...
In recent years, many time synchronization protocols for wireless sensor networks are presented and reducing the number of synchronous data packets in transmission has become a new research breakthrough. In this paper, the nodes with amount of power held are placed in different areas where the two nodes may exchange the synchronization information. This way does not only efficiently use of energy...
Coverage and connectivity are both attractive issues in wireless sensor networks. Both of them are important measurements of quality of service (Qos). Coverage configuration is an effective method to alleviate the energy-limitation problem of sensor nodes, while network connectivity is an unelectable problem guaranteeing the network usefulness. Existing researches promoted many protocols to configure...
