... for both Channel MAC and IEEE 802. 11. With the number of nodes, the received throughput increases rapidly in Channel MAC as compared to IEEE 802. 11. For n = 10, Channel MAC outperforms IEEE 802. 11 ... in this figure for comparison. End- to-end packet delay versus P for both Channel MAC and IEEE 802. 11 in single-hop case is shown in Figure 8.Ina single-ho...

... bands as in- band forwarding, and the transmission on an additional unlicensed band as out-of- band forwarding. In- band forwarding is normally used in TypeImultihopnetworks[12],whereasinTypeIImultihop networks, ... separates the forwarding and access traffic. In so doing, from the access traffic standpoint, the repeaters behave as if they are BSs. In the forward link of wireless systems,...

... utility-energy tradeoff into a Lagrangian form and leave the CPU and network constraints in place. This results in a problem in the form of the single- resource multicell constrained optimization problem ... Networking Instead of having the constraint B i inside a maximization operator, we have only a linear combination of the utility analog A i and the constrained functions B i . The...
