A Comparative Study of Recently Proposed Key Management Schemes in Wireless Sensor Network

Key management is the active research area in security of Wireless Sensor Network (WSN). There are many key management scheme proposed based on usability and benefits depending upon the type of WSN application. The paper presents the comparison and analysis of various recent development in key management schemes with a list of major issues and open research challenges. The survey contains the major aspects of existing key management scheme and provided comparison table 4 which helps in selection of appropriate protocol according to their WSN application. This paper surveys key management development using comparing and literature review of schemes proposed for the last few years to explore how various key distribution schemes help to improve security in WSN.
