The dramatically reduced processing and elimination of re-contending at every hop will significantly reduce latency.
Capacity will be significantly increased by virtue of cooperative transport and switching at the physical layer by eliminating the delay bottleneck, allowing path capacity to better approximate link capacity.
Path diversity along with the use of cooperative transport significantly increases path robustness.
Energy consumption will be reduced due to the reduced processing and contention, and the use of cooperative diversity.
FDesign Approach (Cont.) – Relay PL
Use a proactive link-state routing approach.
The PAC in s1 sends a Segment Access Request (SAR) which gets relayed at the physical layer until it encounters an ongoing transfer.

Accelerate development of both design and implementation by enabling parallelization of effort.
When subsystems are standardized and used across many applications, the per unit cost is reduced, which in turn increases usage.
Individual modules can be upgraded without necessitating a complete system redesign, which would stifle further development and longevity of the system.
Packets are transported over several hops. At each hop, the receiver receives not just the intended signal, but also the superposition of the interfering transmissions of other nodes, plus ambient noise. The interfering transmissions are treated as noise, and the packet is fully decoded. The regenerated packet is then rebroadcast to the next node.
