For practical deployment of wireless sensor networks (WSN), WSNs construct clusters, where a sensor node communicates with other nodes in its cluster, and a cluster head support connectivity between the sensor nodes and a sink node. In hybrid WSNs, cluster heads have cellular network interfaces for global connectivity. However, when WSNs are active and the load of cellular networks is high, the...

Wireless Sensor Networks (WSNs) are one of the most widely used technologies in our daily lives. However, since wireless sensor networks are based on communication within radio channels, WSNs are susceptible to malicious attempts to block the channel. One of the most frequently used attacks is a jamming attack. This type of attack not only blocks the ongoing communication but also exhaust the e...
