USS-TDMA: Self-stabilizing TDMA Algorithm for Underwater Wireless Sensor Network

Underwater wireless sensor network is often constrained by limited power, limited communication range and high bit error rate (BER). We focus on designing a TDMA service for a cube-based underwater wireless sensor network. Such network is readily found in many applications in the area of monitoring, hazard detection, and so on. In this paper, we propose an underwater self-stabilizing TDMA algorithm for assigning time slots to sensors. We present the TDMA algorithm customized for different communication patterns, namely, broadcast, convergecast and local gossip, which occur commonly in sensor networks. The algorithm is self-stabilizing and energy efficiency. Meanwhile, with the localization service, the algorithm can be used in mobile sensor networks.
