Abstract—Because the global positioning system (GPS) consumes a large amount of power and does not work indoors, many virtual-coordinate-based routing protocols are proposed for ...
While wireless sensor networks (WSNs) are typically targeted at large-scale deployment, due to many practical or inevitable reasons, a WSN may not always remain connected. In this...
Simulators are needed for testing algorithms of wireless sensor networks (WSNs) for large scale scenarios. Deploying real WSN testbed provides a more realistic testing environment...

Abstract— The 802.15.4 WSN standard provides optional reliability through positive acknowledgments. Since positive-ACKs are not designed for energy efficiency, there is significa...
—In wireless ad-hoc sensor networks, an important issue often faced in geographic greedy forwarding routing is the “local minimum phenomenon” which is caused by deployment ho...
