In modern measurement technology, wireless sensor network has been widely used in the industrial and other fields. Threrinto,remote virtual measurement technoligy which use wireless network technology to obtain remote measuring data is a hot topics.In this paper,we ues wireless sensor networks to achieve remote measuring data,its emphases is the remote data transfer after measurement ,storing and...
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 MtimesN square area and select a working node in each grid to reduce redundant information and save energy. Secondly, cluster head is dynamic voted...
Wireless sensor networks (WSNs) have received more and more attention on the object tracking system, but the performance of active routing is low. In this paper,we present an novel energy efficient dynamic target tracking (EE-DTT) protocol for wireless sensor network, EE-DTT has three obvious features: firstly, it improves virtual grid ideas to divide each cluster into MtimesN square area and select...
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 energy utility by changing the activity of wireless...
A new cross-layer urgent bit first (CLUBF) scheduling mechanism is proposed and analyzed in the paper. The proposed algorithm focuses on cross-layer resource allocation scheme for heterogeneous services in orthogonal frequency division multiplexing access (OFDMA) downlink systems. And the CLUBF scheduling mechanism is operated over four steps: (1) traffic mapping: dividing traffic into UB (urgent...
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 activity of wireless communication module...
