Wireless Sensor and BAN Wireless Sensor and Body Area Networks

- Consist of a (potentially) large number of devices with

sensor or actuator functionality.

-Broad range of applications and services

-Broad range of bandwidth requirements and network

topologies

-May interact with other networks in close proximity (‘instant partner communication”)

-Devices may be ‘always-on’ or ‘low duty cycle’

-Devices may be ‘context aware’

Motivation and Problem

Anytime and anywhere outdoor assistance requires

1) formation of first response groups wherever

emergency events occur

-Not only medical personnel, but also friends,

neighbors, and passer-by can contribute

2) the interactions among first responders needed to

make rapid decisions in unexpected situations

-to coordinate assistance tasks depending on user

skills, location, and device characteristic

Goals

Design of a BAN that allows the interchange of information among the nodes in the network and the individuals.

Implementation of a BAN that takes significant data in real time to facilitate health-care treatment monitoring amongst firefighters.

To achieve a low-power consumption BAN with routing protocols that optimizecommunications

Phase 4Phase 4

Quantitative analysis to determine if the BAN is a cost-effective technology that can be implemented to help firefighters, as well as a technology that could be introduced in many other areas

Methodology Sensor Network

Look for the sensors, calibrate and testing the sensors.

Establish the connection between the Master Node and Sensor Network.

Master Node Configuration

Setup the Master Node in order to allow the connection between the sensors and the USRP.

USRP Configuration

Design network system in order o receive data package from the Master Node, test the USRP and design a network system in order to deliver data packages to the PC.

Computer or device interface

Use a computer as the interface between the user and the USRP. Complete the priority protocols, create python script for interfacing with USRP.

Graphical User Interface (GUI)

Develop a friendly user graphical interface to present relevant information to the user.

USRP/GNU Radio Testing

GNU Radio Companion (GRC)

Graphical tool for creating signal flow graphs and generating flow-graph source code.

Every block in GRC has a corresponding xml file that contains parameters, IO ports, and a template for code generation.
