Survey on Security aspect of WSN

چکیده
Recently, the tremendous growth in processor, memory, and wireless technology have enabled the development of distributed networks of small, lightweight and cost effective nodes that are capable of sensing the data, computing according to need. Wireless sensor networks (WSNs) are collections of a large amount of small devices equipped with integrated sensing and wireless communication capabilities [3]. These are considered as a special case of ad hoc networks with reduced mobility. Sensor networks share some important characteristics with ad hoc networks, for example they share the need for self-organization, wireless multi-hop operation, and time-variability in topology. The sensor networks are expected to find widespread use in a variety of applications. Environmental monitoring, condition based maintenance, habitat monitoring, seismic detection, military surveillance, inventory tracking, smart spaces etc are some examples. Designing wireless networks with strict layering principle did not fulfil the expectation raised in wire line network design. Due to dynamic nature, infrastructure less architecture, limited resources, mobility of nodes and time varying unstable links and topology, the ad hoc mobile networks oppose strict layered
