A crucial issue for data collection in wireless sensor networks is that the energy consumption of the sensor nodes placed near the sink is very high. This is because the sensors placed near the sink have to forward the data to the sink on behalf of others resulting in the depletion of energy quickly, which will lead to network partitioning and limitation in the network lifetime. In order to sol...
We address the problem of maximizing the lifetime in a wireless sensor network with energy-constrained sensor nodes and mobile data collection points (sinks). Information generated by the monitoring sensors needs to be routed efficiently to the location where the sink is currently located across multiple hops with different transmission energy requirements. We exploit the capability of the sink...
This paper present a low-cost yet effective localization scheme for the wireless sensor networks. There are many studies in the literature of locating the sensors in the wireless sensor networks. Most of them require either installing extra hardware or having a certain amount of sensor nodes with known positions. The localization scheme we propose in this paper is range-free, i.e., not requirin...
This paper presents a novel scheme for self configured dynamic sensor networks based on zones, where sensor nodes are location aware. Location about which sensors provide information is always more important than identification of sensors. It is vital to deliver this information to sink involving minimum packet processing at intermediate nodes due to limited battery life and bandwidth. This sch...
Eastern forests of the US are valued both as a carbon sink and a wood resource. The amount of biomass that can be harvested sustainably from this biome for bioenergy without compromising the carbon sink is uncertain. Using past literature and previously validated models, we assessed four scenarios of biomass harvest in the eastern US: partial harvests of mixed hardwood forests, pine plantation ...
