A Review On Security Issues In Wireless Sensor Networks

Abstract

With increasing dependency on technology, Wireless Sensor Networks (WSNs) had gained more and more popularity in the areas of communication, sensing and computing among investors as well as researchers over the years. The proceeds had since been able to simplify complexity in sensing networks, revealing previously unnoticed observable facts. Major research activities being carried out in this field includes deployment, localization, synchronization, architecture, middleware, security, designing less power consuming devices, abstractions and higher level algorithms for sensor specific issues. However, WSN designs still exhibits security issues in their applications that are of concern. This paper explains a synopsis of ongoing research activities, various security problems involved in wireless sensor networks and possible solutions. The paper also reviewed into the various types of successful attacks carried out on these devices to provide future researchers with clues on how to improve their designs
