The authors of the paper build a heterogeneous surveillance sensor network concerning the relay transmissions of the sensor network nodes among and within the clusters, based on which a binary work node is built to ensure balanced energy consumption of the network. An analysis is also made on the service life of the network in bin-packing conditions, following which an optimal solution is found to...
Wireless sensor network is expected to be deployed in intersection to monitor the traffic flow continuously, and the monitoring data can be used as the foundation of traffic light control. In this paper, a traffic information and transmission system based on Zigbee and wireless sensor network is built, and the sensor nodes used in traffic flow surveillance are developed. Structure, hardware and work...
Wireless sensor networks as sensor technology, microelectronics and wireless communication technology product of the combination, become an active field of computer science research branch, in the military and civilian applications has been widely. As WSNs is limited to low-power requirements of sensor nodes and nodes generally carry an energy which limited and non-replacement, the method which maintains...
For the purpose of enhance the security of poor working in coal mine, it's important to study on the problem of location and tracking for keeping mining personnel and down hole equipments safe. We put forward wireless sensor network underground location algorithm which is based on the superposition of RSSI and DV-Hop. This algorithm makes up for the shortage of RSSI algorithm and DV-Hop algorithm...

The heterogeneous surveillance sensor network can balance the energy consumption better than homogeneous one, and cellular can cover the whole surveillance field without any gap or overlap. Based on the preconditions above, the authors propose the energy consumption and network lifetime models of heterogeneous surveillance sensor network in the condition of cellular coverage. The optimal solution...
Due to the receiving energy consumption on wireless sensor networks routing algorithm has not been considered in past studies, we show in this paper a network model considering both the transmitting and receiving cost. Based on the model, the authors present a new routing algorithm which provides the path with sufficient energy to complete the transmission task. The new algorithm prunes the network...
