Abstract

In this paper, we study hybrid contention-free/contention-based traffic management schemes in presence of delay-sensitive and delay-insensitive data in multihop CDMA wireless mesh networks. We suggest a greedy incremental contention-based ordering algorithm for contention-free schedules and also propose a time-scale-based framework for integration of contention and contention-free traffic management schemes. Further, for the contention-free phase, we propose a power control algorithm that gives an end-to-end throughput guarantee. With the aid of simulation, we observe the additional end-to-end throughput that can be achieved when scheduling and tight power control are applied.
