Early researches focused on the security of homogenous sensor networks. However, recent works have demonstrated that the presence of heterogeneous sensor nodes gives better performance than homogenous ones in terms of energy consumptions, storage overhead, and network connectivity. In this paper, we propose a hierarchical key management scheme named HERO(More)
Recently, it has been shown that heterogeneous wireless sensor networks (HWSN) outperform homogeneous WSN. However, security is still the critical issue. In this paper, we study the impact of node capture attack on three key management schemes designed for heterogeneous wireless sensor networks (HWSN): Asymmetric Pre-distribution key management (AP scheme),(More)
