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 …

In wireless sensor networks, the sensor nodes collect data, which are routed to a sink node.
Most of the existing proposals address the routing problem to maximize network lifetime in …

In this paper we deal with the network lifetime maximization problem under multiple mobile
sink environments, namely, the h-hop-constrained multiple mobile sink problem, which is …

In this paper we explore the mobility of a mobile sink in a wireless sensor network (WSN) to
prolong the network lifetime. Since the mechanical movement of mobile sink is driven by …

Recently, sink mobility has been shown to be highly beneficial in improving network lifetime
in wireless sensor networks (WSNs). Numerous studies have exploited mobile sinks (MSs) …

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 …

This paper investigates heuristics to control and coordinate the concurrent movement of
multiple sinks for lifetime maximization in a wireless sensor network (WSN). We have …

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 …

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 …

Maximizing the lifetime of energy constrained wireless sensor networks is a very challenging
issue. It has been demonstrated that the use of a mobile sink can significantly increase the …
