Certain investigations on secure routing schemes for replica node detection in wireless sensor networks

Abstract

Wireless Sensor Networks (WSNs) are one of the emerging technologies in the 21st century. The interaction between humans and environment is enhanced to a new level with the use of WSNs. In recent years, WSN fascinates both the academic and industrial communities of researchers. WSNs consist of memory-efficient devices that are cheap, use less power and have small transmission range of communication with each other. In spite of their resource-constraints, WSNs are gaining popularity over a decade due to the availability of cheap solutions for numerous challenging real-world problems. Sensors sense the environmental parameters and transmit them to the base station or within them in single/multi-hop manner. Due to the scarcity of resources like battery power, processing capabilities, communication, memory and deployment of large number of sensor nodes, multi-hop is preferred for communicating messages. newline
