Scheduling for Variable Power and Rate Control for Spatial TDMA in Wireless Ad Hoc Networks.
2003 (English)Conference paper (Refereed)
Multihop ad hoc wireless networking is alternative for the communications inareas where there is a scarcity of telecommunications infrastructure. A major design issue in such networks is the formulation of the Medium Access Control(MAC) protocols. Spatial TDMA (S-TDMA) is a `conflict-free'MAC protocol thus enabling high spectral utilization, however the scheduling is required. In link oriented S-TDMA the schedule specifies when particular radio links will be activated. In most wireless networks simultaneous link activation or `reuse' is possible. An efficient schedule is critical tonetwork performance. This paper investigates power and rate control in anS-TDMA ad hoc wireless networks. We present EPR S-TDMA (S-TDMA with enhance power and rate control) scheduling algorithm, that substantially improves throughput performance, when compared to fixed power and rate. The algorithm presented can provide shorter schedule frame duration in comparison withTraffic-sensitive S-TDMA algorithm.
