Security for Multi-hop Communication of Two-tier Wireless Networks with Different Trust Degrees

Many effective strategies for enhancing network performance have been put forth wireless communications’ physical-layer security. Up until now, communications security and privacy optimized based on a set assumption the reliability or tiers of certain nodes. Eavesdroppers, unreliable relays, trustworthy cooperative nodes are just few examples various sorts that frequently categorized. When working sharing information one another, in networks may not always perfect trust another. Modern networks’ be enhanced large part by optimizing levels. To determine path with shortest total transmission time between source destination while still ensuring private messages routed through untrusted tier, we novel approach. Toexamine effects transmit SNR, node density, percentage illegitimate components, simulation results provided.
