Topology control is an effective method to improve the energy efficiency of wireless sensor networks (WSNs). Traditional approaches are based on the assumption that a pair of nodes is either "connected" or "disconnected." These approaches are called connectivity-based topology control. In real environments, however, there are many intermittently connected wireless links called...
Topology control is an effective method to improve the energy efficiency of wireless sensor networks (WSNs). Traditional approaches are based on the assumption that a pair of nodes is either "connected" or "disconnected". These approaches are called connectivity-based topology control. In real environments however, there are many intermittently connected wireless links called lossy...
Reliable transmission service is in dire need for many applications in wireless sensor networks (WSNs). Most existing routing protocols however, seriously suffer from low end-to-end success rates in real deployments. Through extensive experiments on a test-bed of Mica2 nodes, we identify three key problems that hinder the reliable packet delivery. In order to address these problems and therefore to...
