Virtual cells for infrastructureless MANETs

Mobile ad-hoc networks (MANETs) are deployed and operate in infrastructure-less environments. However, when the nodes in such networks are aware of their locations, a shared grid of virtual cells can be defined. It is then possible to pre-assign these cells with communication channels and other radio resources to facilitate distributed radio resource management (RRM) and to limit the exchange of control messages. The channel allocations in virtual cells can assume similar channel reuse schemes as those used in the legacy cellular networks. Assuming that the node clusters coincide with the virtual cells, the average signal-to-interference-noise ratio (SINR) is numerically compared for a random waypoint mobility (RWM) model with a deterministic component, and two sample designs of the orthogonal frequency hopping patterns assigned to the clusters of 3 and 7 virtual cells, respectively.
