Security issues in wireless sensor networks

Abstract

The main purpose of Wireless Sensor Networks (WSNs) is to collect data from unsafe environments. Almost all WSN security protocols assume that an adversary may gain complete control of a sensor node through direct physical access. As sensor networks emerge as a key technology in the future, researchers have faced a number of challenges. A wireless sensor network is made up of many tiny sensor nodes that operate independently and, in some cases, have no access to renewable energy sources. Additionally, as security is essential to the acceptability and use of sensor networks for a variety of applications, there are a number of challenges with sensor networks. This research focuses on the issues in Wireless Sensor Networks.
