Abstract : In high density (HD) mesh networks, packet losses
can occur due to co-channel interference (asynchronous interference)
or collisions (synchronous interference). In this paper,
we first propose a novel method of estimating the probability of
collision and interference statistically. Further, we integrate this
differentiation method with physical carrier sensing adaptation in
a novel centralized algorithm to improve the aggregate throughput
in HD mesh network. Extensive simulations results show
that the on-line algorithm approaches the optimal throughput
predicted by analytical models.
