Enhanced Security in Wireless Sensor Networks
نویسنده
چکیده
Increased demand for Wireless Sensor Networks(WSNs) in fields such as the military, ecological survey and health related areas which deals with sensitive information has imposed the overhead of security in such networks. Attacks on wireless sensor networks have justified the importance of security in this field. Constraints on memory, computation, energy and transmission range associated with WSNs makes security a challenging task to implement. This paper mainly discusses the security aspects of wireless sensor networks in terms of cryptographic implementations and secure routing strategies based on the survey and researches made with emphasis on the architectural limitations of sensor nodes. This paper also discusses the scientific methods involved in each of the chosen strategies by comparing, analysing and evaluating them.
