In energy constrained wireless sensor networks, energy conservation techniques are to be applied in order to maximize the system lifetime. We tackle the problem of increasing netw...
Due to the fragility of small sensors, their finite energy supply and the loss of packets in the wireless channel, reports from sensors may not reach the sink node. In this paper ...
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 many reliable Wireless Sensor Network (WSN) applications, messages have different priorities depending on urgency or importance. For example, a message reporting the failure of...
Maximizing system lifetime in battery-powered wireless sensor networks with power aware topology control protocols and routing protocols has received intensive research. In the pa...
