摘要：A wireless sensor network typically consists of large number of low-cost densely deployed sensor nodes that have strictly constrained sensing, computation, and communication capabilities. Because of resource restricted sensor nodes, it is necessary to reduce the amount of information transmission so that average lifetime of sensor and thus the bandwidth consumption are improved. As wireless sensor networks are typically deployed in remote and hostile environments to transmit sensitive data, sensor nodes are in danger of node compromise attacks and security issues like data confidentiality and integrity are terribly necessary. Therefore, in this paper we have explored general security threats in wireless sensor network and made an extensive study to categorize available data gathering protocols and analyze possible security threats on them.
