On Constrained Power Control for Spatial TDMA in Multi-hop Ad Hoc Radio Networks

• A very attractive alternative for communications in areas in which there is little or no telecommunications infrastructure is to use Multi-hop packet radio networks (MPRNet:s). One major design issue in MPRNet:s is the formulation of Medium Access Control (MAC) protocols. Spatial TDMA (S-TDMA) is a `conflict-free' multiple access for MPRNet:s, which ensures that a packet transmission, whenever made, is successful . Since the transmitter power is at a premium in wireless systems, it is important to utilize it in an efficient way. High S-TDMA system capacities can be achieved by incorporating traffic load information into the MAC protocol design. However, the impact of power control in traffic-sensitive Spatial TDMA schemes control has not received enough attention in the literature. A suitable power control scheme has been chosen and applied to S-TDMA. The resulting delay performance, as determined via network simulations, is presented in this paper. As would be expected the introduction of power control markedly improved the delay performance of Traffic Sensitive S-TDMA.
