Introducing mobility to Wireless Sensor Networks (WSNs) puts new challenges particularly
in designing of routing protocols. Mobility can be applied to the sensor nodes and/or the sink …

In this paper, we investigate the theoretical aspects of the nonuniform node distribution
strategy used to mitigate the energy hole problem in wireless sensor networks (WSNs). We …

, 证明在节点非均匀分布的圆形网络中, 如果节点持续向Sink 节点发送数据 …

Wireless sensor networks (WSNs) form an important part of industrial application. There has
been growing interest in the potential use of WSNs in applications such as environment …

Wireless sensor networks (WSNs) have attracted much attention in recent years. In the many-
to-one WSNs, the nodes located around the sink relay the data from other sensor nodes …

Unbalanced energy consumption is an inherent problem in wireless sensor networks
characterized by multihop routing and many-to-one traffic pattern, and this uneven energy …

A wireless sensor network (WSN) has to maintain a desirable sensing coverage and
periodically report sensed data to the administrative center (ie, base station) and the …

Due to the imbalance of energy consumption of nodes in wireless sensor networks (WSNs),
some local nodes die prematurely, which causes the network partitions and then shortens …

In multi-hop routing, cluster heads near the base station act as relays for far cluster heads
and thus will deplete their energy very quickly. Thus, hot spots in the sensor field result. This …

Due to the limitation of energy resources, energy efficiency is a key issue in wireless sensor
networks (WSNs). Clustering is proved to be an important way to realize hierarchical …
