Wireless Sensor Network consists of tens or thousands of
sensor nodes scattered in a physical space and one or
more Base stations or Sinks. Even thought developed for
military applications now they find a wide variety of
civilian applications also. Some of the applications are
Target tracking, Animal monitoring, Vehicle monitoring.
The need (or lack thereof) for reliability in a sensor
network is firmly dependent upon the specific
application the sensor network is used for. Some
applications like re-tasking or reprogramming sensor
nodes [upgrading software or algorithms, adding codes,
scripts etc] over -the-air requires assured delivery of
high-priority events to sinks. We believe that as the
number of sensor network applications grows, there will
be a need to build more powerful general-purpose
hardware and software environments capable of
reprogramming or retasking sensors to. / Wireless sensor network is a special form of wireless networks
dedicated to surveillance and monitoring applications
Reliability in wireless sensor network is application specific.
The specific form of reliability might change from application
to application. Our idea is to generate reliability based transport
protocol that is customizable to meet the needs of emerging
reliable data applications in sensor networks and is also
adaptive when the nodes are mobile. In our approach, clusters
are formed for minimizing energy dissipation. The nodes
maintain a neighbor list to forward data and any changes in the
local topology can trigger updates to a node’s neighbor list. If a
node notices that its neighbor list has changed, it can
spontaneously re-advertise all of its data thus providing reliable
transport in mobility conditions also. Our approach has five
phases-setup, relaying, relay initiated error recovery, selective
status reporting and node supervising. Our simulation results
prove that the proposed approach can outperform existing
related techniques and is highly responsive to the various error
and mobility conditions experienced in sensor networks.
