A SURVEY OF SECURITY VULNERABILITIES IN WIRELESS SENSOR NETWORKS
Sensor networks offer a powerful combination of distributed sensing, computing and communications. They lend themselves to countless applications and at the same time offer numerous challenges due to their peculiar nature which primarily are their stringent energy constraints to which sensing nodes typify and security vulnerabilities. Security concerns constitute a potential stumbling block to the impending wide deployment of wireless sensor networks (WSNs). Current developments in WSN protocols have not taken security into consideration. On the other hand, the salient features of WSNs make it very challenging to design strong security protocols while still maintaining low overheads. In this paper we provide a survey of typical attack scenarios on WSNs and provide some viable solutions while also elaborating on a number of important security issues.
