System Design, Simulations, Network measurements,
Sensor Networks have applications in diverse fields. They
can be deployed for habitat modeling, temperature
monitoring and industrial sensing. They also find
application in battlefield awareness to sense chemicals
and other gases used in chemical and biological warfare.
An application that has become increasingly attractive in
the post 9/11 era is the use of wireless sensor networks for
emergency (first) response in mass casualty incidents.
Reliability of data and event transfer is of critical
importance to emergency response applications. In this
work we propose a reliable event transfer mechanism
making use of an overlay network of relay nodes. The
overlay network removes the burden of data relaying from
the sensor nodes and results in increasing the lifetime of
the network. Simulation results prove the benefits of such
an architecture. Reliability is increased 10-30% with
reduction in event traffic of 60-80%.
