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...
One of the key problems for wireless sensor networks (WSNs) is the design of energy-efficient routing algorithm, because sensor energy is limited. The energy-efficiency routing algorithm has a strong impact on the network performance. In this paper, we present an energy-efficient minimum routing algorithm (EEMR) of wireless sensor networks. EEMR improves energy utility by changing the activity of...
Sensing connectivity and sensor coverage in sensor networks are two fundamental issues, which have been extensively addressed in the literature. The reliability of wireless sensor networks (WSN) depends on both network connectivity and sensing coverage. Most existing work on sensing coverage has focused on the full coverage problem. However, in some application scenarios, full coverage is either impossible...
