Wireless magnetic sensor networks offer an attractive, low-cost alternative to inductive loops
for traffic measurement in freeways and at intersections. In addition to providing vehicle …

Recent technological advances and the continuing quest for greater efficiency have led to
an explosion of link and network protocols for wireless sensor networks. These protocols …

Wireless magnetic sensor networks offer an attractive, low-cost alternative to inductive loops,
video and radar for traffic surveillance on freeways, at intersections and in parking lots. The …

Time synchronization is a critical building block in distributed wireless sensor networks.
Because sensor nodes may be severely resource-constrained, traditional time …

The common belief is that a multi-hop configuration with rather small per-hop distance is the
only viable energy-efficient option for wireless sensor networks. We discuss a single hop …

The broad problem we address is to support multi-hop flows in a wireless ad-hoc network. In
such networks, achieving predictable quality of service is difficult due to interference …

Many distributed multiple access (MAC) protocols use an exponential backoff mechanism. In
that mechanism, a node picks a random backoff time uniformly in an intervals that doubles in …

Wireless sensor systems contain new types of computing machines and run different kinds
of applications in a variety of physical environments, which offers many challenges. The …

Summary Field Gathering Wireless Sensor Networks are a class of sensor networks used to
periodically collect data from a field in which the sensors are deployed. Sensing data are …
