Jamming and Jamming Discovery Techniques in Wireless Sensor Networks
Abstract
Jamming in WSN is a primary challenge faced because of the ease of blocking WSN con-tact. Jamming problems are a subset of service-based denial attacks in which affected nodes pre-vent legitimate contact by causing deliberate interference in communication networks on a recur-sive basis. To understand this problem, different strategies for jamming and anti-jamming in WSN need to be addressed and analysed in detail. Specific jamming localisation, countermeas-ure and identification methods are researched to tackle jamming difficulties. The key characteris-tics of jamming methodologies and their types of jammers, and positioning jammers for efficient jamming. In this paper the open problems such as jammer recognition and energy-efficient detec-tion schemes in this area
