Abstract
Clustering technology is one of the crucial technologies to prolong the lifetime in wireless sensor networks. However, most cluster schemes choose cluster head randomly to send data without considering load balancing and security. In addition, some cluster heads in the highly active area may be overloaded, while others in the low active area may be overloaded, which may easily lead to extreme imbalance in task allocation. Our research on relevant literature shows that the existing authentication schemes do not fully consider the load balancing of cluster heads, while the load balancing schemes ignore the security authentication of cluster heads. Therefore, this article effectively combines load balancing and security verification, and proposes a lightweight load balancing and verification scheme (secure load and energy balancing) based on clustered wireless sensor networks. Secure load and energy balancing implements cluster head’s authentication and confidentiality and integrity of all messages in load balancing. This scheme not only effectively maintains the energy balance of the whole network but also successfully improves the security overhead, thus prolonging the network lifetime. The simulation results show that compared with other similar schemes, this scheme has higher packet forwarding rate, longer network life, and lower overhead. This further proves that the scheme is energy-saving, safe, dynamic, stable, and sustainable.

Wireless sensor network (WSN) consists of a variety of sensors distributed in space, which are used to monitor and sense the environment, such as temperature, humidity, light, sound, vibration, pressure, location, and even military terrain, and to transmit data to the base station (BS) through the network for processing.[1]
In order to solve the problem of load and energy balance, various new research technologies have been proposed, but they cannot solve the problem of cluster heads (CHs) security deployment and verification at the same time
All the time the secure load and energy balancing (SLEB) achieves better packet forwarding ratio than the other schemes MS-LEACH, S-LEACH, and SS-LEACH protocols. This is because in SLEB, malicious CHs cannot join into the network through authentication, the identity of all malicious nodes cannot be verified, and sending data packets will be ignored by normal CH
Summary
Wireless sensor network (WSN) consists of a variety of sensors distributed in space, which are used to monitor and sense the environment, such as temperature, humidity, light, sound, vibration, pressure, location, and even military terrain, and to transmit data to the base station (BS) through the network for processing.[1]. In order to solve the problem of load and energy balance, various new research technologies have been proposed, but they cannot solve the problem of CH security deployment and verification at the same time. Dynamic load balancing uses a more real-time approach by considering the current load and energy on a single CH and recommending the target CH . Existing deployment technologies authenticate network nodes without obtaining target loading information and residual energy. This poses new challenges in building dynamic load and energy balance through appropriate deployment and authentication. The approach combines the above dynamic load and energy balancing data with deployment and authentication, and applies them to clustered WSNs. The performance of the scheme is evaluated and simulated, and the effectiveness and stability of the scheme are verified.
