Sender Authentication with Transmission Power Adjustment Method Using RSSI in Wireless Sensor Network
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
With the advent of powerful and efficient wireless sensor nodes, the usage of wireless sensor networks (WSN) has been increased greatly. Sensor networks consist of a network of autonomous sensors that can reconfigure themselves so as to sense the environment in the most efficient manner. These nodes are having low power and limited range. Low power implies limited battery life. In WSN, to perform the task successfully low energy consumption is the major concern. Wide use of WSN in practical application makes it necessary to maintain the network security.IP or MAC addresses are used for sender authentication which can be spoofed easily. This makes these types of networks vulnerable to many identity-based attacks. To protect wireless network from such type of attacks, Received Signal Strength Indicator (RSSI) value called ‘Signalprint’ can be used for sender authentication, which is harder to spoof. However in WSN battery discharge causes received signal characteristics to vary. This may give false alarm in sender authentication. Low energy consumption is one way to mitigate this problem.
