Security Enhancement Strategies in Wireless Sensor Networks - A Survey

Abstract

The great qualities as well as fast data transfer through one location to the other using wireless technologies for communication is causing a rapid progress in this field. Security constitutes one of the biggest challenges in Wireless Sensor Networks [WSNs], relying mostly on applications deployed. There are many different security measures that have been suggested to protect the privacy of information in WSNs. With those strategies come disadvantages like security flaws. In this work, a security-related survey is undertaken. Because of their physical restrictions in terms of both size and power, WSN influence the adoption of security greatly. We also present the pro’s and con’s of several existing models with their implementation in WSN. The importance of QoS was also a very important one to know the performance of the various models in terms of security.
