The document proposes two techniques - periodic collection and source simulation - to prevent leakage of location information in sensor networks from a global eavesdropper. Periodic collection provides high location privacy while source simulation provides tradeoffs between privacy, communication cost, and latency. The techniques are efficient and effective at providing source and sink location privacy compared to existing methods that only defend against local adversaries.

3. ABSTRACT
 We propose two
techniques that prevent
the leakage of location
information: periodic
collection and source
simulation.
 Periodic collection
provides a high level of
location privacy, while
source simulation
provides trade-offs
between privacy,
communication cost,
and latency.

4. ARCHITECTURE

5. EXISTING SYSTEM
 Existing solutions
can only be used to
deal with
adversaries who
have only a local
view of network
traffic.

6. DISADVANTAGES OF
EXISTING SYSTEM
 Existing techniques
defend the leakage
of location
information from a
limited adversary
who can only
observe network
traffic in a small
region.

7. PROPOSED SYSTEM
 We show the
performance of the
proposed privacy-
preserving techniques
in terms of energy
consumption and
latency and compare
our methods with the
phantom single-path
method, a method
that is effective only
against local
eavesdroppers.

8. ADVANTAGES OF PROPOSED
SYSTEM
 The proposed system
provides trade-offs
between privacy,
communication cost,
and latency.

 The proposed
techniques are
efficient and effective
for source and sink-
location privacy in
sensor networks.

 1. Attackers
Modules.
 2. Privacy-
Preserving Routing
Techniques.
 3. Adversary Model.
 4. Privacy
Evaluation Model.
 5. Security Analysis.

10. 1. Attackers Modules:
 In this module we
form the WSN
network area and the
appearance of an
endangered animal
(Attackers) in a
monitored area that is
survived by wireless
sensor, at the each
time the inside and
outside sensors are
sensing to find out the
attackers location and
the timing.

11. 2. Privacy-Preserving Routing
Techniques:
 In this module
presents two
techniques for
privacy preserving
routing in sensor
networks, a periodic
collection method
and a source
simulation method.

12. 3. Adversary Model:
 For the kinds of
wireless sensor
networks that we
envision, we expect
highly-motivated and
well-funded
attackers whose
objective is to learn
sensitive location-
based information.

13. 4. Privacy Evaluation Model:
 In this module, we
formalize the location
privacy issues under
the global
eavesdropper model.
In this model, the
adversary deploys an
attacking network to
monitor the sensor
activities in the target
network.

14. 5. Security Analysis:
 The generation
number of a packet
can be hidden in the
secure routing
scheme through
link-to-link
encryption. In this
way, attackers
cannot find the
generation number
of a packet for their
further analysis.
