Embodiment Construction

[0047] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0048] In the EAR protocol of the related art, a global flooding method is adopted to establish routes. Although the purpose of evenly distributing network energy consumption and prolonging the network life cycle can be achieved, the establishment stage is very complicated. Although the GBR protocol adopts the traffic expansion method to prolong the network life cycle better than the random method, but when using the expansion method, it must try to avoid using bottleneck nodes in the network, and each node must maintain the distance between itself and its neighbors. Gradient information between.

[0049] In view of this, the present invention proposes a concept of local flooding, proposing to flood and establish routes within a local range determined by a set affinity. In order to set the closeness, the present invention designs an...

Abstract

The method comprises: a) building a routing table comprising the proximity between neighboring node and current node; b) according to the routing table, the data of source node is routed to the destination node. The invention also reveals a routing device.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a routing method and device. Background technique [0002] In recent years, due to the development of microelectronics technology, computing technology and wireless communication technology, mobile ad hoc (Ad Hoc) network has become one of the hotspots of researchers all over the world. As a typical application of mobile ad hoc network, the wireless sensor network is composed of countless sensor nodes, which form a multi-hop ad hoc network through wireless communication, collects and processes data and sends it to users or task managers. It has very broad application prospects: environmental monitoring and forecasting, medical care, smart home, monitoring, transportation, exploration, and logistics management and safety monitoring, etc. [0003] The mobile ad hoc network has great limitations in terms of computing power, energy and memory capacity, and usually its appl...
