2.  Intrusion detection plays an important role in the area of security in WSN.  WSN consumes a lot of energy to detect an intruder. Therefore we derive an algorithm for energy efficient external and internal intrusion detection.

3.  Intrusion detection is defined as the art of detecting inappropriate, inaccurate, or anomalous activity.  Today, intrusion detection is one of the high priority and challenging tasks for network administrators and security professionals.

4.  A Wireless Sensor Network (WSN) is a collection of spatially deployed wireless sensors by which to monitor various changes of environmental conditions (e.g., forest fire, air pollutant concentration, and object moving) in a collaborative manner without relying on any underlying infrastructure support.

5.  In a WSN, there are two ways to detect an object (i.e., an intruder): ◦ single-sensing detection ◦ multiple-sensing detection  In the single-sensing detection, the intruder can be successfully detected by a single sensor.  On the contrary, in the multiple-sensing detection, the intruder can only be detected by multiple collaborating sensors.

6.  An Intrusion detection system (IDS) is software and/or hardware designed to detect unwanted attempts at accessing, manipulating, and/or disabling of computer mainly through a network, such as the Internet.

8.  The intrusion distance is referred as D and defined as the distance between the points the intruder enters the WSN, and the point the intruder is detected by the WSN system.  The value of D must be minimum.  D=Distance b/w the point at which intruder enters WSN and the point at which intruder is detected.

9. Existing System  In single-sensing detection, at a time only one intruder detected by the WSN.  Our Previous work was according to homogeneous and heterogeneous single sensor in wireless sensor network. Proposed System  In Heterogeneous wireless sensor, Intruder detected anywhere in the network.  We are detecting the intruder in multiple sensor heterogeneous wireless sensor networks.

15. CONSTRUCTING NETWORK SECURITY  In this module, we are going to connect the network, each node is connected to the neighbouring node and it is independently deployed in network area.  And also deploy the each port no that is authorized in a node. RANDOMIZED FIELD DETECTION  In this module, browse and select the source file.  And selected data is converted into fixed size of packets.  And the packet is send from source to detector.

16. LAYERED APPROACH FOR INTRUSION DETECTION  The LIDS draws its motivation from what we call as the Airport Security model, where a number of security checks are performed one after the other in a sequence.  Similar to this model, the LIDS represents a sequential Layered Approach and is based on ensuring availability, confidentiality, and integrity of data and (or) services over a network.

17. FIND AUTHORIZED AND UNAUTHORIZED PORT  If path is authorized the packet is send to valid destination.  Otherwise the packet will be deleted. CONSTRUCTING INTER-DOMAIN PACKET FILTERS  If the packet is received from other than the port no it will be filtered and discarded.  This filter only removes the unauthorized packets and authorized packets send to destination.

18. RECEIVING THE VALID PACKET  In this module, after filtering the invalid packets, all the valid Packets will reach the destination.
