MeshScape System Overview
on-demand data model is a medical monitoring application where patients in a hospital wear
sensors to monitor vital signs and doctors access that data via a PDA that is a mobile gateway. A
doctor enters a room and the mobile PDA automatically binds with the network associated with
that patient and downloads vital sensor data. When the doctor enters a second patient's room,
the PDA automatically binds with that network and downloads the second patient's data.
Broadcast Data Models
Broadcast data models are characterized by a need for one-to-many communication between
the gateway/application and sensor/actuator nodes. The MeshScape system supports the
broadcast data models described in this section.
Burst
The burst data model is characterized by an uneven pattern of data transmission from the
gateway/application to all sensor/actuator nodes on the wireless sensor network. The burst data
model has been used with industrial lighting applications.
Stream
In the stream data model, the gateway/application sends data in a continuous stream to all
sensor/actuator nodes on the wireless sensor network. The transport service guarantees that all
data is delivered to the other end in the same order as sent and without duplicates. The stream
data model is used when performing network upgrades.
Low-Power Configuration
Many sensors are dispersed over a wide area and must rely on batteries or solar cells for their
power source. Consider the example of sensors taking measurements on a gas pad, it would be
prohibitively expensive to network these sensors using cables, so a wireless sensor network is
the perfect solution. However, to be useful in such an environment, the wireless sensor network
must posses the following characteristics:
• Power: Low power consumption—sensor and node must be able to operate 10+ years on
a singe battery
• Scalability: End nodes must be able to scale as sensor node counts increase.
• Data Rate: Application/gateway must support a configurable sample rate.
• Range: End nodes must be able to communicate over distances of 60 to 80 feet (18 to 24
meters) and Mesh nodes must be able to communicate at distances up to 100 feet (30
meters).
• Integration: The end nodes must be integrated with the sensor.
The MeshScape system possesses all of theses characteristics and uses configurable sleep and
duty cycle intervals to minimize power consumption.
