  1. 1. By Lokanath Reddy Wireless Sensor Network Security Issues
  2. 2. Table of Contents: Introduction Data aggregation Security issues Applications Future scope Conclusion
  3. 3. Introduction:  Large number of sensor node devices spread over a large field.  Wireless sensing + Data Networking.
  4. 4. Introduction:  Low power devices  Consists of- one or more sensors, a processor, memory, a power supply.  Formed by hundreds or thousands of nodes.
  5. 5. Data aggregation:  In wireless sensor network the numbers of sensors are very large.  the processing of data will need the battery consumption gets increased  The solution is the minimizing the data. Here the data minimization will do by the data aggregation.  The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced.
  6. 6. Data aggregation:
  7. 7. Security Issues:  Limited Resources – All security approaches require a certain amount of resources for the implementation. – Resources are very limited in a tiny wireless sensor.  Limited Memory – Sensor is a small in size so that the storage capacity of data is also small. – In wireless sensor devices have the limited memory.
  8. 8. Security Issues:  Power consumption – In sensor network sensing is the higher priority task. – This process always in execution so that there is a need of high performance battery.  Unreliable transfer – Wireless sensor network uses the the connectionless routing. – The possibility of channel error rate may increase.
  9. 9.  Process Management – A military example is the use of sensors detect enemy intrusion.  Health care monitoring – Body-area networks can collect information about an individual's health, fitness.  Environmental/Earth sensing – Air pollution monitoring – Water quality monitoring ApplicationsApplications:
  10. 10. Future scope:  Everything on Internet  Everybody on Internet  Technology to – interconnect individual smart devices – Enable access to information about the real world
  11. 11. Future scope:
  12. 12. Conclusion  The sensor network uses the huge number of sensor devices. Due to sensing device each node need to process the data.  When there is a processing then energy loss will happen. To reduce the energy loss data aggregation can apply.
