In order to reduce the complexity of searching relay nodes and the average number of hops from source node to destination node in the process of forwarding, an adaptive routing protocol based on forwarding angle (ARPBFA) in vehicular ad hoc networks (VANETs) is proposed. Forwarding angle and the average distance of one-hop progress are the two key parameters of the routing protocol. Simulation results...
To resolve channel interference and "Deafness" problem in cognitive wireless mesh network, a new Cross-layer Design based on Link Quality for Cognitive Wireless Mesh Networks is proposed. When the node chooses the channel, it is not only in accordance with the rank of channels, but also based on link quality. In this way, cross-layer technology can be effectively achieved, and network performance...
Greedy geographic routing is attractive in wireless sensor networks because of its efficiency and scalability. This paper presents an up-down links dualpath greedy routing (UDLDGR) protocol for wireless sensor networks. The routing protocol not only reserves the features of greedy forwarding algorithm, which is simple, efficient, but also uses different relay nodes to serve as routing nodes for up...
Nodes perceived environment and selected the appropriate route for business transfers in Cognitive Wireless Mesh Network. However, the variation of spectrum holes results in the change of routes which brings negative effects on the data transmission. An adaptive multi-path algorithm that uses reinforcement learning based on multi-agent is proposed in this paper. Better route can always be obtained...
Multiple channels can increase network capacity by transmitting traffic on different channels in an interference area. Firstly, an efficient distributed joint routing and channel allocation strategy for cognitive wireless mesh networks is proposed in this paper. The main purpose of this channel allocation strategy is to maintain the channel diversity in the neighborhood channels. Simulation results...
