摘要：Many research papers proposed deploying mobile sink node or nodes within a wireless sensor network to collect data from static sensor nodes. Thus, the performance of the wireless sensor network can be improved and its life time can be prolonged. In this paper, a new sink mobility model that is based on the breadth first traversal of a graph is proposed. As a result, the mobile sink will traverse the sensor network and visit static sensor nodes to collect data according to movement paths that are calculated based on the breadth first algorithm. After that, the proposed mobility model is simulated using NS-2 simulator and the performance of the proposed model is studied under different network sizes and speeds. Finally, average end-to-end delay, packet delivery ratio and throughput are the performance parameters used to study and investigate the behavior of the network using the mobility model proposed in this paper.
