Sažetak In this paper we address the problem of maximizing the lifetime in a wireless sensor
network with energy and power constrained sensor nodes and mobile data collection point …

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 …

It is a known phenomenon that in a wireless sensor network, sensors communicating directly
with a sink deplete their energy faster than the others. As a result, the so-called neighboring …

Recent work shows that sink mobility along a constrained path can improve the energy
efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink …

With the advances of more and more mobile sink deployments (eg, robots and unmanned
aerial vehicles), mobile sinks have been demonstrated to play an important role in the …

We address the problem of maximizing the lifetime of a wireless sensor network with energy-
constrained sensors and a mobile sink. The sink travels among discrete locations to gather …

Wireless sensor networks basically consist of low cost sensor nodes which collect data from
environment and relay them to a sink, where they will be subsequently processed. Since …

In this paper we investigate the benefits of placing optimal number of sinks for a wireless
sensor network (WSN) to prolong the network lifetime, provided that the number of hops from …

Network lifetime maximization is challenging particularly for large-scale wireless sensor
networks. The sensor nodes near the sink node tend to suffer high energy consumption due …

Unbalanced energy depletion is a well-known problem in wireless sensor networks which is
causing hot spot problem as a result of multi-hop communication to forward data to the static …
