System and method for achieving generalized routing protocol of wireless sensor network

Abstract

The invention provides a system for achieving a generalized routing protocol of wireless sensor network, which comprises a user interface module and a routing protocol module, wherein the user interface module maps a user requirement as a user instruction which is sent to the routing protocol module, and the routing protocol module processes topology information in the network according to the received user instruction. The invention also provides a method for achieving the generalized routing protocol of the wireless sensor network, which comprises the following steps: generating the user instruction according to user requirements; mapping the user instruction as a route selection criterion; and processing the topology information in the network according to the route selection criterion. The system and the method solve the problems of the flexibility and the generality of the routing protocol in the wireless sensor network.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a system and method for realizing a general routing protocol of wireless sensor networks. Background technique [0002] The wireless sensor network is composed of a large number of micro sensor nodes integrating wireless communication, information collection and information processing functions. Each sensor node uses its own sensor to collect information in the surrounding environment, and then transmits the information to the data aggregation node (sink node) in the network. [0003] Due to the large network coverage, direct communication between sink nodes and sensor nodes is often impossible. When beyond the direct communication range, the sensor node needs other nodes to help it transmit information to the sink node in the way of multi-hop relay. Similarly, if the user has an accusation command that needs to be sent to some sensor nodes, this message must also be tra...

This will seriously affect the completion of the information collection task, and even in some occasions it cannot be done at all

[0007] At the same time, the routing metrics and routing criteria that are tightly coupled with specific requirements also make it impossible for a routing protocol developed for one application to be applied to another, and the compatibility between different sensor networks is poor.
