Abstract

Sensors networks are often constrained by limited power and limitedcommunication range. If a sensor receives two messages simultaneouslythen they collide and both messages become incomprehensible.In this paper, we present a simple time division multiple access(TDMA) algorithm for assigning time slots to sensors and show thatit provides a significant reduction in the number of collisions incurredduring communication. We present TDMA algorithms customizedfor different communication patterns, namely, broadcast,convergecast and local gossip, that occur commonly in sensor networks.Our algorithms are self-stabilizing, i.e., TDMA is restoredeven if the system reaches an arbitrary state where the sensors arecorrupted or improperly initialized.
