	abstract = {Energy efficient operation is of paramount importance in wireless sensor networks. In this paper we propose a novel solution to rterrea.se energy consumption by adaptively moving the sink node. We assume an event driven scenario, where only a reduced number of activated sensors report to the sink node. We also assume that these events have to be reported in real-time, a requirement that makes the existing random or controlled sink mobility solutions inappropriate. We define three different strategies to adaptively move the sink node; the goal is to reduce the communication distance, and thus the energy consumption, of the reporting nodes. The efficiency of the strategies is evaluated through simulations.},

	abstract = {Optimizing energy consumption in wireless sensor
		networks is of paramount importance. There is a recent trend to
		deal with this problem by introducing mobile elements (sensors
		or sink nodes) in the network. The majority of these approaches
		assume time-driven scenarios and/or single-hop communication
		between participating nodes. However, there are several real-life applications for which an event-based and multi-hop operation
		is more appropriate. In this paper we propose to adaptively
		move the sink node inside the covered region, according to
		the evolution of current events, so as to minimize the energy
		consumption incurred by the multi-hop transmission of the eventrelated data. Both analytical and simulation results are given
		for two optimization strategies: minimizing the overall energy
		consumption, and minimizing the maximum load on a specific
		sensor respectively. We show that by adaptively moving the sink,significant power saving can be achieved, prolonging the lifetime of the network.},
