Abstract
The unique characteristic of the wireless sensor network is the limited battery of the nodes in the network. To save their batteries, the nodes in the network are usually clustered into groups, with the member nodes forwarding data to the sink via their cluster head. The sink in the network can be mobile or fixed. To support sink mobility, it is crucial to provide means to reach the mobile sink node. Since frequent location updates from mobile sinks can generate excessive energy consumption of sensors, routing strategies handling sink mobility should provide efficient ways for the tracking of sinks in order to keep all sensor nodes updated for the future data reports. This paper presents a data collection scheme using the mobile sink. The performance of the network has been analyzed on the basis of packet delivery ratio, throughput and routing overhead. These parameters have shown an improvement over the existing scheme.
