in emerging sensing technology. They are used in various fields such as military operations, healthcare applications, traffic control, and home applications. Even sensor can monitor, pressure, humidity, noise level, temperature, soil makeup and other properties. Wireless Sensor Network can be of consist of different types of sensors like thermal, visual, infrared, acoustic and radar. Wireless Sensor Network (WSN) is broadcast nature of the wireless communication so it becomes easy for the attacker to send false data or false information to compromise the entire network due to which there are high chances that causes problem in making decision. Here the solution proposed is MAC (Message Authentication Code), Authentication is necessary for many administrative tasks informally; data authentication allows a receiver to verify that the data really is sent by the claimed sender. If the message is from claimed sender then the message or information is accepted or if the message is from not from the claimed sender then the message or information is not accepted.
1. INTRODUCTION The Wireless Sensor Network (WSN) consists of sensors that are tiny in size and have the capability of sensing things and communicating with other devices, over a specific area. They are low cost solutions for variety of real world applications. Wireless Sensor Network (WSN) sensors are small in size and low power. Also the main problem of the sensor is that it has very low storage, so whatever algorithm or program is written for securing the network, it has to very small and efficient in order to work properly. Wireless Sensor Network (WSN) is broadcast in nature means the network can be compromised by the attacker. The attacks can target any node, this can lead to leak secret information and interfering message which ultimately violates security. Therefore authenticity is a mandatory service for securing Wireless Sensor Network (WSN), because message modification or message falsification is problems that need to be solved.
Network Manager: - It is responsible for configuration of the network scheduling.
New nodes or devices can be added at any time.
All nodes can be accessed through centralized monitoring system.
Since it is wireless in nature so it is cost efficient as it does not require wires and cables.
They can be used in variety of domains such as military, healthcare, agriculture, mines etc.
Disadvantages of Wireless Sensor Network (WSN):
Architecture of Wireless Sensor Network (WSN): Wireless Sensor Network (WSN) consists of following components:
Impact Factor value: 7.529

Sensors have low storage and low powered battery.
It cannot be used for high speed communication due to low bandwidth.
It is wireless in nature, so it can be hacked easily by the attacker.
It is expensive to build such network.
