Abstract :
We study the problem of placing erasure nodes among passive stations in a slotted dual bus network. Erasure nodes are known to improve throughput by allowing slot reuse. It is also known that choices made in locating erasure nodes significantly impact network congestion and overall throughput-especially when traffic patterns exhibit a high degree of locality. We present algorithms to determine optimal placements of erasure nodes that improve upon prior work on this problem: we present simpler and faster polynomial-time algorithms and also consider various useful cost measures. These algorithms can be used to solve related placement problems in which limits on congestion and existing placements are given as input, and the goal is to find the minimum number of erasure nodes required to meet the congestion bound
