In Wireless Sensor Networks (WSNs), controlling transmission power is a commonly used technique to extend battery life. This paper describes a novel mechanism using measured RSS (Received Signal Strength) to calculate optimal transmission power. This technique works in multipath environments and with nodes with differing transmission capability. Our technique achieves automatic configuration employing...
The main goal in wireless sensor networking remains the reduction of the network lifecycle and the enhancement of its reliability, keeping decent performances in terms of throughput and latency. Given the increasing interest of the research community on wireless network coding (NC), we think such challenges can be tackled using its innovative concepts, especially in the case of many-to-one communications...
In battery-driven multi-hop wireless sensor networks, the most highly burdened relay nodes, or bottleneck nodes, will die first. These deaths eventually partition the network and trap valuable battery energy in the network. In a multi-hop wireless sensor network that must harvest energy from weak energy sources, the nodes that are one hop away from the Sink must sometimes shut down to harvest, so...
