Abstract
Spectrum management using a radio environment map (REM) to dynamically allocate frequencies may facilitate the efficient exploitation of the spectrum in a heterogeneous environment. The overhead costs of networking radios to create the map must be balanced against the impact of a poor REM due to low quality or quantity of sensor data. To study the cost-benefit balance of two routing protocols, simulations were performed to evaluate the transmission of REM data using Ad hoc On-Demand Distance Vector (AODV) routing and Optimized Link State Routing (OLSR). It was seen that both protocols caused significant overhead in the system, effectively reducing the amount of data that could reach the data collection centre, and thus potentially lowering the quality of the resulting REM.
