Due to its own features including variability of network topology, instable vehicle density and so on, Vehicular Ad hoc Networks (VANETs) can hardly guarantee efficient and reliable network connectivity which plays an important role in data dissemination. Compared with VANET, cellular networks is of great advantage to provide timely data propagation. To solve the problem of disconnection in VANET,...
In this paper, we propose a multi-sink data transfer protocol for wireless sensor networks, called negotiation-based multi-sink data transfer (NMDT). NMDT is based on the packet flooding method, but the direction of packet flooding in each sensor node is dynamically controlled, taking into consideration the network traffic around the sensor node. Thus, stable sensed data transfer and collection can...
