Cooperative neighbor discovery and access control protocol based on power broadband carrier

Abstract

The invention discloses a cooperative neighbor discovery and access control protocol based on a power broadband carrier. The protocol comprises the following steps that waking time of the station in the high-speed carrier communication network is set as the multiple of the prime number, the prime number is automatically selected by a global calculator of the neighbor discovery protocol, and an expected station work period or discovery delay is matched when each multiple of the prime number is selected; the station selects a work period or discovery delay, and obtains the minimum discovery delay of the work period; the station acquires communication neighbor information, and executes an access control protocol after completing verification of all communication neighbors; a real neighbor isidentified based on the positioned routing distributed protocol, and a relay station is selected to forward data through multi-point relay routing; the neighbor discovery protocol is realized in the broadband power line carrier communication network, and data packet forwarding efficiency can be improved; the protocol has good discovery performance, minimum discovery delay and maximum work period;the security is relatively high, and the site discovery delay can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of broadband carrier, in particular to a cooperative neighbor discovery and access control protocol based on power broadband carrier. Background technique [0002] With the popularization and rapid development of the Internet, IPv4 has revealed many disadvantages, such as lack of address resources, low quality of service, lack of mobility, weak automatic configuration capabilities, and poor security. Transition is an inevitable trend in the development of the Internet. The Neighbor Discovery Protocol is a basic protocol in the Ipv6 protocol suite, which provides functions such as router discovery, stateless address autoconfiguration, duplicate address detection, link layer address resolution, and neighbor unreachability detection for network sites. The Neighbor Discovery Protocol works at the network layer and is responsible for discovering other sites and corresponding addresses on the link, determining av...
