ABSTRACT

Intrusion detection plays an important role in the area of

security in WSN (wireless sensor n/w). Detection of any type

of intruder is essential in case of WSN.

WSN consumes a lot of energy to detect an intruder. Therefore

we derive an algorithm for energy efficient external and

internal intrusion detection. This paper considers single sensing

and multi sensing intruder detection models.

SYSTEM ANALYSIS

EXISTING SYSTEM

single-sensing detection, the intruder can be successfully

detected by a single sensor Previous work was according to

homogeneous single sensor in wireless sensor network

It is because individual sensors can only sense a portion of the

intruder.

PROPOSED SYSTEM

Intrusion detection in heterogeneous WSNs by characterizing

intrusion detection with respect to the network parameters.

Two detection models are:

Single-sensing detection

Multiple-sensing detection models

These are two detection models

We are detecting the intruder both single sensor and multiple

sensor heterogeneous wireless sensor network.

CONCLUSION• This Project speaks about the minimization of external

intrusion detection in an energy efficient way and probability of intrusion detection in a heterogeneous WSN deployed in a two dimensional space.

• This probability gives an insight in to the required number of sensors in a given deployment, their sensing and transmission range to efficiently detect an intruder in a given WSN. We have developed an analytical model for intrusion detection and applied the same into single-sensing detection and multi-sensing detection scenarios for heterogeneous WSNs. The correctness of analytical model is proved by simulation.
