A novel efficient forwarding protocol (NEFP) for 3-D underwater wireless sensor networks (UWSNs) is proposed in this paper. Three strategies are adopted in NEFP. Firstly, the forwarding zone is presented to avoid the unnecessary forwarding. Secondly, in order to balance the energy consumption and reduce the collisions between the neighboring nodes, the time interval of the nodes for holding the received...
The railway environment monitoring system is very crucial to ensure the safe operation of the High-speed railway. This paper addresses the problem of the nodes deployment of WSN-based railway environment monitoring system. Our design goal is to find the optimal deployment scheme (number of relay node and the deployment of these nodes) that maximize the network utilization efficiency defined as network...
An adaptive forwarding protocol (AFP) for 3D Flying Ad Hoc Networks (FANETs) is proposed in this paper. The main objective is to calculate forwarding probability adaptively in order to increase the efficiency of forwarding in FANETs. The Unmanned Air Vehicle (UAV) nodes with longer distance to the last hop forwarder and closer to the destination rebroadcast the message with higher probability. In...
At present most of the WSNs routing protocol only have a single research objective. The overall network performance lacks of multi-objective inspection and evaluation. The basic task of multi-objective routing is to find a route in the network which has sufficient resources to optimize some network parameters and satisfy multiple constrains. A multi-objective model, constrained of bandwidth, is put...
Wireless multimedia sensor networks (WMSNs) models emphasize QoS guarantee. We provide QoS guarantee to measure the qualitative performance of QoS routing model, such as bandwidth, delay and delay jitter. A path that satisfies with the QoS is found by the Directed Diffusion (DD) algorithm in this paper, and an incomplete information game routing model is presented under this condition. We show that...
Saving energy, lowering energy consumption and reducing pollutants discharge was an important factor of effecting economic development. This is a new research direction to use super capacity to crane system. In this paper, the character of the super capacitor was firstly introduced and analyzed. Secondly, the DC-DC converter used in crane system based on mix power was designed. And the technology...
Scientific forecast is of great importance to the economic phenomenon research and economic decision-making. Therefore, the research about economic forecast theory and method is always a hot topic. This paper proposed an algorithm combined with the grey model, least square method and topology model, which can be a new advanced algorithm for forecasting. Using this new algorithm, the paper forecasts...
