Partitioning WCN models for parallel simulation of radio resource management

Parallel Simulation techniques have been proposed as a possible solution to execution time and memory constraints often found in detailed simulations of Wireless Cellular Networks. However, partitioning represents a major cha llenge for models that encompass elements of radio propagation phenomena. T his paper discusses the partitionings problem with respect to Parallel Disc rete Event Simulation and we formulate an approach to study partitioning of a WCN model that includes radio propagation. Various options for a model o f moderate size and where interference is calculated over the whole system are evaluated through experimentation and some limited mathematical analysi s. Results indicate that radio spectrum based partitioning is preferable to geographically based partitionings for this model in many realistic scenar ios. It is also noted that characteristics of the model differ sufficiently from other previously studied spatially explicit problems to reduce or eve n annihilate the effectiveness of some commonly used partitioning technique s.
