High Performance Communication Framework for Mobile Sinks Wireless Sensor Networks
… networks. Many researchers have proposed using mobile sinks as one possible solution to improve the lifetime of wireless sensor networks. The reason is that the typical manyto- one communication traffic pattern in wireless sensor networks imposes a heavy forwarding load on the nodes close to the …

Cluster-based trust proliferation and energy efficient data collection in unattended wireless sensor networks with mobile sinks
… such as a storm or a volcanic eruption, mobile sinks must be used to gather data. We aim to introduce a fast cluster-based mechanism by which nodes can securely connect to one another based on trust and network clustering and begin transmitting data to a collection device while it is …

Modeling Crowd Mobility and Communication in Wireless Networks
… modeling, wireless sensor networks (WSNs) with mobile sinks, and opportunistic communication in theme parks. The two main directions of our contributions are human mobility models and strategies for the mobile sink positioning and communication in wireless networks. The first direction of the …

Spatial modelling and analysis of wireless ad-hoc and sensor networks: an energy perspective
… model for a sensor network including sinks, compressors and sensors. We show that the optimal organization is associated with the Johnson-Mehl tessellation induced by nodes’ locations. Our analysis and simulations show the proposed scheme can yield 8-28% energy savings depending on the …
