Method for realizing light location service in Ad Hoc network

Abstract

The invention discloses a method for realizing light location service in an Ad Hoc network, which combines a neighbor list and a position database to realize the location tracking of a target node, thereby fulfilling the request / response task of a location service. The method realizes the expenses of only the establishment and the maintenance of the neighbor list and the position database, and both the expenses are restricted to the interaction of backfence control information, therefore, large scale and remote periodical position information updating expense is eliminated, so that control load caused by location service is greatly reduced; and the requested node self-execute position response to ensure the freshness of the response information. The method has the advantages that the method is simple and feasible; the expansibility is good; and the position information is kept to be fresh, particularly in a large-scale Ad Hoc network.

Description

A Light Location Service Implementation Method in AdHoc Network technical field The invention is applied in a wireless mobile self-organizing network (AdHoc network), mainly relates to a location service realization method of a routing layer, and provides service support for a routing protocol based on a geographic location. Background technique Among the various routing protocols currently used in wireless mobile AdHoc networks, the routing protocol based on geographic location is recognized as a routing method with good scalability and effectiveness. All geographic location-based routing protocols are based on two common assumptions: firstly, all network nodes can accurately know their real-time location information, and secondly, all nodes can know the location information of the destination node before communication. The first assumption can be realized by positioning systems such as GPS, and the second assumption needs to be supported by the location service of the Ad...

Problems solved by technology

However, the overall load of location services is still too large, which limits the application of location-based routing protocols to large-scale networks.
