Abstract

In wireless sensor networks (WSNs), previous real-time data dissemination schemes for stationary sinks exploits the spatiotemporal approach, which utilizes the delivery speed based on the fixed distance between a source and a static sink to fulfil the desired time deadline. This approach cannot be directly applied to a mobile sink since the distance can be varied depending on its movement. That is, the delivery speed cannot be determined without knowing the distance between a source and a mobile sink. It must be the hardest problem for all intermediate sensors to know the current location update of the mobile sink and control their transmission speeds. We focus on the real-time data dissemination for a slowly varying mobile sink compared to the transmission speed, which may be the most common case. By the slowly varying constraint, the movable area of a mobile sink can be determined by the two factors: its speed and the distance between a source and its initial location. In this paper, we propose a real-time data dissemination scheme for a mobile sink by utilizing the movable area concept. Simulation results show that the proposed scheme provides a high success ratio in terms of the guarantee of real-time requirement.
