Wireless sensor networks (WSNs) consists of unattended sensors with limited storage, energy (battery power) and computation and communication capabilities. Since battery power is the most crucial resource for sensor nodes, the utility of energy efficient and the maximum lifetime is special important. In this paper, we present an energy-efficient dynamic(More)
Wireless sensor networks (WSNs) have received more and more attention due to the limited energy of battery-powered nodes, but rarely consider the maximum lifetime and the shortest path at the same time. In this paper, we present an energy-efficient algorithm for maximum lifetime and minimum routing (EE-MLMR) in wireless sensor networks. EE-MLMR improves(More)
One of the most critical issues in wireless sensor networks is represented by the limited availability of energy on network nodes; thus, making good use of energy is necessary to increase network lifetime. In this paper, we present an energy-efficient maximum lifetime (EEML) algorithm in wireless sensor networks. EEML improves energy utility by changing the(More)
A particular wireless sensor networks (WSNs), cluster-based WSN (CWSN) have received more and more attention due to the limited energy of battery-powered nodes, but rarely consider the shortest path at the same time. In this paper, we propose an novel energy-efficient routing protocol based on clustering and least spanning tree for wireless sensor network(More)
The Distributed Coordination Function (DCF) in the IEEE 802.11 protocol is a random access scheme based on the carrier sense multiple access with collision avoidance (CSMA/CA). In recent years, there have been numerous research on the performance analysis and model of DCF under the assumption that the transmission queue is always nonempty (i.e. saturation(More)

For monitoring burst events in reactive Wireless sensor networks(WSNs),an novel energy-efficient dynamic voting cluster (EE-DVC) algorithm is proposed. EE-DVC has three obvious features: Firstly, it adopts virtual grid ideas to divide each cluster  into M×N square area and  select a working node in each grid to reduce redundant(More)
An induced voltage Electromagnetic Flow meter (EMF) in the area of measuring single phase flow rate in pipes has been used in many industrial areas. To measure the continuous phase velocity profile in multiphase flows where the continuous phase is electrical conductive, Electrical capacitance and resistance tomography has been comprehensively investigated,(More)
