In this article we present a simple yet accurate generic analytical model for a family of slotted CSMA/CA-based MAC protocols widely used in various wireless broadband access networks. The proposed model is based on a hierarchical three-level renewal process concept, which leads directly to some important MAC protocol performance metrics, such as throughput and average frame service time. The applicability...
Ad hoc networks are expected to have some critical connectivity properties before partitioning. Timely partition prediction signals action for improving fault tolerance and performing some data or service replication so that the network can continue functioning after partition does occur. This article surveys existing prediction concepts and discusses their scalability, simplicity, correctness, speed,...
