One of the key issues in Wireless Sensor Networks (WSN) is the hot-spot problem ie the
nodes closer to the sink tend to drain their energy at a faster rate when compared to other …

The connectivity of radio frequency (RF) devices is usually limited by their predefined
bandwidth. Due to stochastic selection of cluster heads, most wireless sensor networks …

This article studies the effect of partial coverage to extend the lifetime of wireless sensor
networks and introduces a hybrid exact solution strategy that efficiently maximizes network …

In this paper, the influence of the features of the propagation channel in the performance of
energy-efficient routing algorithms for wireless sensor networks is studied. Although there …

The issue of hotspot occurs when the sink neighboring nodes drain more energy and
become dead early. For a time being the whole network is isolated due to dying nodes and …

Sensor nodes deployed outdoors are subject to environmental detriments and often need to
cache data for an extended period of time. This paper introduces sensor nodes which are …

针对无线传感器网络分簇结构中簇头节点能量消耗过快而容易死亡的问题,
提出了一种适合于水稻田监测的混合天线组网通信的能量异构双簇头分簇路由算法 …

With the emergence of Wireless Sensor Networks (WSNs), a large number of academics
have worked over the last several decades to increase energy efficiency and clustering …

In low-duty-cycle wireless sensor networks, the lifetime of energy-limited nodes is improved,
but the network's transmission delay is also increased. However, many systems with real …

The lifetime of Wireless Sensor Networks (WSNs) can be extended with the adoption of an
effective clustering method. However, the major problem of a multihop-based clustered …
