Throughput Analysis of the Frequency Hopping Technique Against Malicious Node Attacks in Wireless Sensor Networks
Wireless Sensor Networks (WSN) is the recent concept in the networking field that consists of a large number of tiny nodes capable of sensing, processing and transmitting data. Most routing protocols are designed with the aim to decrease power consumption at the cost of security. The insecure nature of the wireless channels and the fact that packets can easily be tampered with, makes wireless sensor networks easily prone to internal and external attacks. Thus security is a major requirement to ensure the transmission and reception of reliable data in a WSN. Many of the standing routing algorithms developed for WSN's are susceptible to attacks in hostile environments. An important security concern is the threat of a malicious node.
