In this paper, we propose a two-tiered Distributed Hash Table (DHT) based overlay for an implementation of publish/subscribe. In this overlay, upper tier consists of stable nodes with more resources whereas lower tier contains less stable nodes with limited resources. In our design, all nodes are required to join at lower tier and nodes with better uptime and resources may dynamically migrate to upper tier. Further, taking the advantage of prevalent skewness in subscription patterns, popular… CONTINUE READING
