A SURVEY ON ATTACKS, SECURITY AND CHALLENGES IN WIRELESS SENSOR NETWORKS

Abstract

A Wireless Sensor Network is a group of spatially distributed autonomous sensor devices. Because of design and cost restraints, the sensor nodes are not prepared with tamper-resistant hardware. Due to the unattended nature, they are more exposed to physical captures by opponents. Main motive behinds this paper is to introduce different types of attacks bump into during broadcast and communiqué over the wireless sensor network and provides some ideas to overcome from these attacks. Security has also been a major concern in these networks due to restrictions of resources in the sensor nodes and less human intrusion during its operation. The power computation and unsecure communication is main challenging area of wireless sensor network.
