Adaptive TDMA-based clustering for critical event detection in Wireless Sensor Networks

Time slot assignment for convergecast in wireless sensor networks

“…Nevertheless, Jung et al presented an algorithm for finding the minimum scheduling time for convergecast in general networks [13]. [17] Stop-and-collect No Any No Annamalai [2] Code allocation Yes TDMA No Moscibroda [16] Network processing Yes TDMA No Gherairi [9] Partial scheduling Yes TDMA No Vasavada [24] Group information Yes TDMA No Villas [25] Spatial correlation Yes Any No Gandham [8] Storage size ≤ 2…”

“…There have also been more recent works that have addressed this problem. For event detection, Gherairi et al presented an adaptive TDMA-based clustering method [9]. To reduce data delivery time and energy consumption, time slots are only assigned to sensor nodes in the event detection area and only for wireless links on paths to the sink node rather than to the entire network.…”
