In a wireless sensor network (WSN), the energy hole problem is a key factor which affects the lifetime of the networks. In a WSN with circular multi-hop deployment (modeled as …
Wireless sensor network (WSN) consists of spatially distributed miniature size and autonomous nodes along with batteries as a power source. The major bottleneck of WSN is …
E Zhao, B Yi, J Yao - 2006 IET International Conference on …, 2006 - ieeexplore.ieee.org
Recent studies show the capacity of WSNs can be significantly increased when the nodes can have variable transmission ranges. It is well known that in wireless sensor networks …
In a wireless sensor network where sensors are arranged into a flat topology, sensors near the sink consume much more energy than sensors at the boundary of the network. Sensors …
Prolonging the network lifetime is a crucial constraint in wireless sensor networks. Since data communication requires a more energy consumption than any other process, sensor …
Summary Wireless Sensor Networks (WSNs) have been widely considered as one of the most important technologies with unique characteristics designed for various applications …
