Enhancement of Energy Utilization by Reliable Routing and Secure Data Transmission in Heterogeneous WSN

Secure data transmission in heterogeneous WSNs is a problem that has been of great importance ever since WSNs became popular. Wireless sensor networks (WSNs) are composed of sensor nodes that collect data in real time and transmit it to a central base station or other nodes, or even another network. Heterogeneous WSNs consists of sensor nodes with different capabilities and characteristics. These heterogeneous networks present a challenge for securely transmitting the data from source to destination. In order to ensure the security of data transmission in these networks, different security methods like encryption, authentication, and authorization have been implemented. Encryption methods such as the Advanced Encryption Standard (AES) and Triple Data Encryption Standard (TDES) are used to protect the data from unauthorized access and modification. Authentication protocols like AAA (Authentication, Authorization and Accounting) are used to verify the identity of the entity at the opposite end of the communication and to prevent unauthorized behavior.
