To compensate the lack of systematicness and realistic model,heterogeneities were classified into several categories,a heterogeneity space model was built up by utilizing space theory,and the variation trend of dynamic heterogeneity was discussed.Then,an energy efficient random key pre-distribution protocol was proposed, which is inspired by dynamic energy heterogeneity.Under a certain heterogeneity space model,several evaluation metrics including long-term network connectivity,resilience and lifetime were also analyzed. Simulation result showed that by rational using of heterogeneity,the proposed protocol doesn’t only keep connectivity and improve resilience,but also provide a much better network lifetime than other protocols.
