Improving network lifetime is a fundamental challenge of wireless sensor networks. One
possible solution consists in making use of mobile sinks. Whereas theoretical analysis …

Mobile sink has been adopted by many schemes for lifetime improvement in wireless sensor
networks. It is necessary to propagate the topological or location changes caused by the …

A critical issue for data gathering in wireless sensor networks is the formation of energy
holes near the sinks. Sensors near the sinks have to participate in relaying data on behalf of …

Sink mobility is one of the most comprehensive trends for information gathering in sensor
networks. This way of information gathering has a prominent role in balancing the energy …

In this paper, we address the problem of packet transmission from multiple sources to
multiple mobile sinks in the large-scale sensor network. Each mobile sink needs to …

This paper explores the idea of exploiting the mobility of data collection points (sinks) for the
purpose of increasing the lifetime of a wireless sensor network with energy-constrained …

In WSN, sensors near the sink have to relay the data of the nodes away from the sink and as
a result they drain their energy very quickly. It result in network partitioning and can …

The concentration of data traffic towards the sink in a wireless sensor network causes the
nearby nodes to deplete their batteries quicker than other nodes, which leaves the sink …

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 …
