Mobility in wireless sensor networks has attracted a lot of attention in the recent years [6] and has introduced unique challenges in aspects like resource management, coverage, routing protocols, security, etc. The next evolutionary step for sensor networks is to handle the mobility effect in all its forms. In this paper, we propose a mobility-aware(More)
One of the mechanisms used to enlarge the lifetime of wireless sensor networks (WSN) and to provide more efficient functioning procedures is clustering. By assuming roles within a cluster hierarchy, the nodes in a WSN can control the activities they performed and therefore, reduce their energy consumption. However, the election of when to act as a data(More)
