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...
In wireless sensor networks (WSNs), timeliness is one of the most challenging problems for critical applications. Caccamo et al. designed a collision-free real-time MAC protocol for sensor networks by adopting the "cellular structure" in traditional telecommunication networks. They assumed that sensors are organized into many rigid hexagon cells and a router node is at the center of each...
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...
Rapid growth in sensor technology and wireless communication has led to the development of wireless sensor networks (WSNs). Due to cost and environment concerns, the battery of sensor is not always rechargeable particularly when the network operates in an inhospitable or hostile field. This study proposed a Lifetime-Extended Uniform Distribution (LEUD) algorithm to provide ubiquitous communication...
