by unnecessary communication. That is indeed a critical situation for energy

• Warm Attack: In a warm attack, an adversary can degrade the system operation by corrupting the system software. It is implied by the malicious code in the node. Once the node becomes the victim of a warm attack it can be denying its service to the neighbor, modifying the information, or may get access to

• Side Channel Attack: This kind of attack wreck the encryption mechanism and get the private key. The attacker breaches the side channel information. Side channel information contains timing information, power consumption or electromagnetic leaks. Catch attack, timing attack, power monitoring attack, acoustic crypto analysis are some of the example of side channel attack.

One solution to that is WSNs must be protected by the powerful gateway. This solution is not feasible in the current infrastructure as it comes with scarce resources in the WSNs [17–20]. It is sheer essential to provide fundamental security measures to the sensor node while connecting to the internet [21]. We can use encryption techniques like symmetric key encryption model or public key encryption model for the communication. To implement the encryption model, it requires a secure key infrastructure that can provide a secure key for communication. It seems fascinating but it is a strenuous task to implement the encryption model in WSNs which comes with a large number of nodes. Moreover, it adds extra overhead to the communication which is an undesirable condition, especially with scarce

important information. Warm is capable to reproduce itself.

Integration of IoT and WSNs enables the broad opportunity in almost every aspect of the life. The integration seems fascination at first look but it comes with unseen challenges. In WSNs, sensor node is equipped with very low resources in terms of hardware as well as software. Operating system of the sensor node has very low processing capacity and its operation is quite different from the internet node. Hardware of sensor node is designed in such way that it consumes less energy and comes in to active mode as and when any event happens. On the other hand IoT has no limitation either in processing capability or hardware compatibility. In the integration, the layered function of WSNs and IoT has to be tailored for the interoperability. Moreover, WSNs node needs to be updated to deal with the security attacks from the internet. Overall for the faithful integration WSNs has to upgrades it capacity and IoT needs to tailor its layered operation so that it can be compatible with WSNs.
