On High Spatial Reuse Broadcast Scheduling in STDMA Wireless Ad Hoc Networks
Ashutosh Deepak Gore · 2006
Graph-based algorithms for point-to-multipoint broadcast scheduling in Spatial reuse Time Division Multiple Access (STDMA) wireless ad hoc networks often result in a significant number of transmissions having low Signal to Interference and Noise density Ratio (SINR) at intended receivers, leading to low throughput. To overcome this problem, we propose a new algorithm for STDMA broadcast scheduling based on a graph model of the network as well as SINR computations. The performance of our algorithm is evaluated in terms of spatial reuse and computational complexity. Simulation results demonstrate that the proposed algorithm performs significantly better than existing graph-based algorithms.
