Judging mobility the stability in the Mobile ad hoc network system of the IP infrastructure at the time of packet reception between the network devices which operate the network device

摘要

PROBLEM TO BE SOLVED: To provide a network apparatus for a stable handoff in an IP-based mobile adhoc network system and a handoff method using this, by stably providing a handoff even when moving to a new access router region.;SOLUTION: The apparatus comprises a mobility decision part which decides mobility by using a signal strength when receiving a packet between the network apparatuses operating on a communication mobile adhoc network and decides a handoff to a new access router, a router setting part which preliminarily performs the handoff to the new access router according to a decision result of the mobility decision part and sets information about the new access router for the handoff, and a handoff processing part which implements the handoff to the new access router by using information that is preliminarily set according to the decision result of the mobility decision part.;COPYRIGHT: (C)2005,JPO&NCIPI
