Abstract

wireless sensor networks (WSNs) are wireless ad hoc networks of tiny sensor nodes. As a result of advances in sensor technology and wireless communication, sensor networks have emerged as an indispensable and important new tool for multiple civilian and military applications, including patient monitoring, wildlife monitoring, battlefield surveillance, enemy tracking, tracking contamination in hazardous environments, habitat monitoring in the nature preserves, traffic monitoring, surveillance of buildings, ecological and health related areas. security is therefore important in WSNs. 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. Keywords: wireless sensor networks (Wsns), sensor, security, Impersonation , Eavesdropping, Denial- Of-Service Attacks
