Information forwarding method in opportunity network based on node excitation

The invention discloses an information forwarding method in a resource-constrained opportunity network based on node excitation, aiming at solving the problems of node blind cooperation and the like of the existing node excitation which fails to take occupation and energy consumption of node cache in the network into consideration. According to the information forwarding method disclosed by the invention, a pricing foundation is set by taking idle cache space, rest energy and owned monetary value on the node as well as size and rest survival time of the message into comprehensive consideration. Hereby, the node, as a rational entity, is scientifically described, and with variation of an environment attribution and variation of cooperative willingness, and depending on an instinct of seeking for owned benefit maximization of the node, rational excitation node cooperation is achieved. Furthermore, when the rest energy of the node is rare, the network service life of the node can be prolonged; and when the idle cache space of the node is comparatively small, the method is favorable for relieving the network jamming, so that the energy consumption can be effectively reduced, and the network average transmission delay and delivery rate can be improved.

Method, device and system for transmitting data

The invention provides a method, a device and a system for transmitting data. The method includes adjusting a lower limit value of an original receiving window by the aid of the size of a preset reordering window to obtain a lower limit value of a current receiving window; comparing the lower limit value of the current receiving window to the lower limit value of the original receiving window, and updating the lower limit value of the original receiving window as a breakpoint value if the lower limit value of the current receiving window is larger than the lower limit value of the original receiving window; transmitting a data packet with a packet sequence number smaller than the breakpoint value to a receiving layer. The lower limit value of the original receiving window is a packet sequence number of a next data packet which is expected to be received by the receiving end. The breakpoint value is a packet sequence number of a first data packet which is not received, and the packet sequence number is not smaller than the lower limit value of the current receiving window. The method, the device and the system in an embodiment of the invention have the advantages that the purpose of shortening the data packet submission delay can be achieved, and jittering of the data packets in transmission procedures further can be reduced.

Route method based on crossroads in opportunistic vehicular ad hoc network

The invention requests to protect a route method based on crossroads in an opportunistic vehicular ad hoc network. In an urban environment, vehicular ad hoc network nodes move at high speeds, and a topological structure changes frequently. Aimed at the problems that an existing router algorithm has many limits, uniform distribution of nodes in the network is neglected, and a selected router is not the optimum router because both history information and network global information are considered, the invention provides the router method based on the crossroads. When a source node has a data sending request and no router reaches a target node, a plurality of routes from the source node to the target node are firstly searched for and established, then factors influencing performance of road segments and crossroads are respectively considered, the performance of the road segments and the crossroads are comprehensively considered, the performance of each router is analyzed, and under the condition that the global information is considered, the optimum router is selected from the plurality of routes for data transmission, so that the network delivery rate is effectively improved, and the average transmission time delay is lowered.
