Securing Distributed Wireless Sensor Networks: Issues and Guidelines

With the emergence of ubiquitous computing the role of sensor network is becoming more important which demands highest level security and energy efficiency. In this paper we have investigated the current available solutions and found that none of the solutions are completely meeting the basic security requirements such as authentication, access control, and non-repudiation, etc. Therefore we have proposed hypothetical framework called Tetra security framework for the distributed wireless sensor networks in order to achieve highest level security and overall energy efficiency.
