摘要: 延迟容忍网络(DTN)中的保管传递机制存在着节点资源不足,束传输不可靠等问题。分析了存储资源的受限对束传输可靠性的影响,并借鉴生物网络机理,提出了基于生物网络的保管传递机制,设计具有免疫行为的生物实体并代理保管束,生物实体通过自组织协作完成保管传递,可以有效地降低分组丢失率。最后以智能服装无线传感器网络为例,通过试验评价该机制及其性能,证明了其有效性。

Abstract: Custody transfer is a proposed DTN reliability mechanism to enhance end-to-end reliability.It can increase packet transmission failures and storage limitation.This paper provides a new custody transfer scheme based on Bio-Network.A custody transfer model is built on a Bio-Network platform.Bio-entities with the characteristics of immune behaviors are designed to take custody.An application of garment-embedded oriented wireless sensor network is analyzed.Results reveal the superiority of the Bio-Network scheme in comparison to the present scheme.

Key words: Delay Tolerant Networks(DTN), Bio-Network, custody transfer, bio-entity
