On the capacity of one-hop ALOHA packet radio networks with adjustable transmission power
Abstract
In this paper two possible policies are investigated for realizing an arbitrary traffic matrix in a Slotted ALOHA broadcast packet radio network: full connectivity and limited transmission power. The performance for the fully connected (point-to-point) network is the same as the known result for a centralized network and allows a maximum throughput of 1/e. The other approach, wherein each node is given sufficient power to just reach his destination, allows a maximum throughput proportional to the logarithm of the number of (active) nodes in the network. These results, which are derived analytically, are then verified by simulation, showing excellent agreement.
