2. OBJECTIVE
To reduce the work load of cluster head
To increase the throughput and reduce the energy
consumption
3. ABSTRACT
The Polling Point in which the DGN is placed and polling
point is common to particular region.
The designed scheme minimizes the energy exploitation,
reduces the end-to-end delay and traffic in cluster head in
WSNs by effective usage of the DCT.
Mainly focus on the problem of minimizing the length of
each data-gathering and refer to this as the single-hop data-
gathering problem (SHDGP).
4. EXISTING WORK
To collect the data from cluster head to sink used to the data
gathering node.
Here the data gathering node was connected along the
VELCT (Velocity Efficient Link Aware Cluster Tree) scheme.
5. PROPOSED WORK
We proposed a novel logical topology for data collection
named Spanning Tree Covering Algorithm in which we create
the polling point for data gathering
6. WORK MODULE
Node Initialization
Define Data Gathering Node
Spanning Tree Algorithm
Define Polling Point
Data collection
Send to destination
8. DISCRIPTION
NODE INITIALIZATION
Organize the sensor nodes into
cluster.
Each cluster member is
governed by a cluster head.
Suitable for data fusion.
Self organizing.
9. POLLING POINT
Polling Point in the sense of creating center point amongst
cluster head.
SPANNING TREE
Spanning tree creates the loops to all clustering nodes.
Find the nearest node.
It will create as a data set of all information.
Depends upon the data set the polling point will be create.
10. SPANNING TREE ALGORITHM
Step 0: Pick any vertex as a starting vertex (call it A). Mark it
with any given color, say orange.
Step 1: Find the nearest neighbor of A (call it B). Mark both
vertex and the edge AB orange
11. SPANNING TREE ALGORITHM
Step 2: Find the nearest uncolored neighbor to the orange sub graph.
Mark it and the edge connecting the vertex to the red sub graph in
orange.
Step 3: Repeat the above step until all vertices are marked orange. The
orange sub graph is a minimum spanning tree.
13. POLLING POINT INITIALIZATION
The spanning covering
algorithm initialized current
empty node as a polling point.
Union current node containing
all sensor nodes and create the
candidate polling points.
All sensor nodes are covered
by corresponding polling
points in the region.
Add the corresponding polling
points cover sensor nodes into
current empty polling point.
Find an approximate shortest
tour on polling point.
19. PERFORMANCE EVALUATION
ENERGY GRAPH
The graph between time
and working efficiency in
joule.
To compare the existing
methods the energy
consumption is increases.
20. PERFORMANCE EVALUATION
THRESHOLD GRAPH
The threshold graph is
drawn between time and
no. of packets transfer to
the sink.
The threshold of these
method is increases the
ratio of PDR.
21. PERFORMANCE EVALUATION
DELAY GRAPH
The delay graph is drawn
between time and delay of
packets.
The packet delay ratio is
reduces the proposed
method.
22. ADVANTAGES
By introducing the polling point data gathering becomes
more flexible and adaptable to the unexpected changes
of the network topology.
Data gathering is perfectly suitable for applications,
where sensors are only partially connected.
Reduces the number of data gathering node in VELCT.
Less transmission delay.
Energy efficient.
23. APPLICATIONS
FIRE BUG
Wildfire Instrumentation System
Using Networked Sensors.
Allows predictive analysis of
evolving fire behavior
Firebugs: GPS-enabled, wireless
thermal sensor motes based on
TinyOS that self-organize into
networks for collecting real time
data in wild fire environments.
24. APPLICATIONS
Preventive maintenance on an oil
tanker.
Use of sensor networks to
support preventive maintenance
on board an oil tanker in the
North Sea.
A sensor network deployment
onboard the ship .
System gathered data reliably and
recovered from errors when they
occurred.
25. CONCLUSION
In this paper spanning tree covering algorithm a proficient
method to construct a mobility based auspicious network
management architecture for WSNs
In this method each cluster member choose the CH with
better connection time and forward the data packets to the
corresponding CH in an allocated time slot.
