Abstract

We look at the power bandwidth trade-off in random sensory and ad-hoc wireless networks with n users and r ≤ √n simultaneous source/destination pairs. Under a specific protocol, we show that the minimum power required for maintaining an achievable scaling law of R_(sum)=Θ(f(n)) for the sum-rate in the network, scales like Θ(f(n)/√n). The required bandwidth B in this case is of order Θ(f(n)/r). It is also proved that the minimum achievable energy per information bit (E_b/N_0)min for this protocol, scales as Θ(1/√n) and in this case the spectral efficiency is nonzero and is of constant order.
