The Complexity of Interval Routing on Random Graphs (1998)
Flammini, M., Van Leeuwen, J., Marchetti-Spaccamela, A.
Several methods exist for routing messages in a network without using complete routing tables (compact routing). In k-interval routing schemes (k-IRS), links carry up to k intervals each. A message...
We present new solutions to the problems of constructing efficient implicit data structures for min-max and min-max-median priority queues. The novelty in our approach is that we use the standard...
Thesis (DIng)-Universiteit van Pretoria, 1988.
An interval routing scheme is a general method of routing messages in a distributive network using compact routing tables. In this paper, concepts related to optimal interval routing schemes are...
