An Instantaneous Data Dissemination Mechanism with Mobile Sinks in Wireless Sensor Network

In wireless sensor networks, sensor nodes will transmit the sensing data to sink through multi-hop, this kind of transmission will cause the hotspot problem, and also the effectiveness of sensing data will be decreased in larger network environment. To solve all these problems, we propose an instantaneous data dissemination mechanism which can use multiple mobile sinks to collect the sensing data. We assume mobile sinks have timer and time synchronized. Mobile sinks will periodically update the time stamp of sensor nodes, nodes will decide to broadcast the sensing data or not by comparing the time stamp when event occur. The sensing data will reach mobile sinks by doing this repeatedly without any location information.
