Survey on Various Key Management Schemes for LEACH in Wireless Sensor Networks
نویسنده
چکیده
Wireless Sensor Network (WSN) are the network of sensor nodes which communicate with each other and with the base station using wireless channel. Due to extensive use of wireless sensor networks it is necessary to improve its security. WSN nodes are prone to physical attacks. Wireless sensor networks (WSN) face security threats so traditional key management schemes are no longer accurate for WSN. There should be some special key management schemes for WSN. The objective of this paper is to provide comparative study of various key management techniques for LEACH in wireless sensor networks with advantages and disadvantages of each scheme. Keywords— WSN, LEACH, CH, SecLEACH, ESKMS, DKS-LEACH
