Latency-Sensitive Power Control for Wireless Ad-Hoc Networks
Overview This paper investigates the impact of power control on latency in wireless ad-hoc networks. If transmission power is increased, interference increases, thus reducing network capacity. A node sending/relaying delay-sensitive real-time application traffic can, however, use a higher power level to reduce latency, if it considers information about load and channel contention at its neighboring nodes. Based on this observation, the paper formulates a new distributed power control protocol, Load-Aware Power Control (LAPC), that heuristically considers low end-to-end latency when selecting power levels. The paper studies the performance of LAPC via simulations, varying the network density, node dispersion patterns, and traffic load.
