SECURITY THREATS IN WIRELESS SENSOR NETWORKS

Sona Malhotra

Wireless sensor networks have been emerged as a challenging and unexplored field for researchers worldwide in the past few years. Wireless sensor networks have a vast range of practical applications. Wireless technology can able to reach virtually every location on the surface of the earth. A wireless sensor network is a network of a large number of independently working small sensing units which communicate wirelessly. It may be used for sensing scalar data events like as pressure, acceleration, temperature, proximity, strain etc. It may also be used to sense multimedia data events and transfer of multimedia data like as audio, video, image etc. In this paper, we have discussed the current situation, hardships in implementation & possible solutions
