Security concerns in WSns

Wireless Sensor Networks (WSN) is one of the trends that has posed numerous challenges for researchers. These networks consists of potentially thousands of tiny sensor nodes, functioning independently, some without access to renewable energy resources. Routing is seen as a major bottleneck in WSN.

wireless sensor networks are extremely vulnerable against any kind of internal or external attacks, due to several factors such as low computation capability, small memory, resource-constrained nodes and lack of tamper-resistant packages, limited energy resources, susceptibility to physical capture. These constraints make security challenging in WSNs. The key issues are discussed here :
