SSIR: Secure SAGSIN IAB Relay Network

SSIR is a comprehensive implementation of multi-hop relaying space-air-ground-sea integrated networks; and an official implementation of the paper titled "-". This repository contains a variety of routing algorithms including A*(or Dijkstra), genetic algorithm, graph convolutional network (GCN), and graph attention network (GAT).

Installation

Pip from source:

git clone https://github.com/hslyu/SSIR
 
cd SSIR
pip install .   

---

Quickstart

from ssir import environment as env

dm = env.DataManager()
pm = env.PlotManager()
master_graph = dm.generate_master_graph()

costs, predecessors_distance = pf.a_star(master_graph, metric="distance")
graph = pf.get_solution_graph(graph, predecessors_distance)

pm.plot_dm(dm, graph)
