Data for: Probability Based Path Discovery Algorithm for Electromagnetic Nano-networks

One of the major challenges for nano-network is the forfeit of communication protocols to exploit the potential communication between nano-machines forming fully operational nano-network. Because nano-machines face some restrictions such as limited processing power and confined computing capabilities, up-to-date nano-machines cannot perceive partial or full routing tables, which are the main decision-makers for data routing in legacy communication networks. The reason is that creating and updating routing tables continuously require adequate processing power with sufficient memory and computing capabilities, which is not the case of nano-nodes. So, new innovative routing schemes have to be proposed for nano-networks to deal with such extremely low resources. This paper focuses on decoupling the routing intelligence from nano-network towards a computational architecture using Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies by externalizing routing decisions and complex computations from nano-nodes to be fully compiled externally. Moreover, the paper proposes a probability-based path discovery protocol denoted by (PBPD) for electromagnetic nano-nodes suitable for dynamic nano-network applications. The performance of the proposed protocol is evaluated and compared with other routing protocols discussed in the literature. The proposed scheme provides low energy consumption inside nano-nodes and low computational complexity thanks to SDN/NFV system.

纳米网络（nano-network）面临的核心挑战之一，是缺乏能够充分挖掘构成完整可运行纳米网络的纳米机器（nano-machines）间通信潜力的通信协议。
由于纳米机器存在处理能力有限、计算能力受限等诸多制约，当前的纳米机器无法感知完整或部分路由表——而在传统通信网络中，路由表正是数据路由的核心决策依据。
究其原因，持续创建和更新路由表需要充足的处理能力、足够的内存与计算资源，而纳米节点（nano-nodes）并不具备此类条件。因此，必须为纳米网络设计全新的创新性路由方案，以应对其极端有限的资源约束。
本文聚焦于将路由智能从纳米网络中解耦，借助软件定义网络（Software Defined Networking, SDN）与网络功能虚拟化（Network Function Virtualization, NFV）技术，通过将路由决策与复杂计算从纳米节点外部化，交由外部架构完成执行。
此外，本文还提出一种面向电磁纳米节点、适用于动态纳米网络应用的基于概率的路径发现协议，记为PBPD。
针对所提协议的性能，本文展开了评估，并与现有文献中讨论的其他路由协议进行了对比。得益于SDN/NFV架构，所提方案可实现纳米节点内部低能耗与低计算复杂度。
