Virtual Energy Based Encryption Keying framework for WSN: A Survey

A wireless sensor network consists of sensor nodes which are resource limited wireless devices and it is difficult to recharge them due to hostile environment. Energy consumption and security are the main concerning factors during transmission in wireless sensor networks. Therefore it is required to consume minimum energy without risking security of wireless networks. Less energy consumption prolongs the life time of the sensor nodes. VEBEK is a secure and energy efficient communication framework which is based on dynamic key generation mechanism using RC4 algorithm and it is able to detect and filter false data injected into the network by malicious outsiders. VEBEK consists two operational modes- VEBEK-I&VEBEK-II. In this paper both the modes of VEBEK has explained.
