Wireless node device route maintenance method in a wireless network, and route maintenance system

摘要

PROBLEM TO BE SOLVED: To eliminate unnecessary route construction processing, processing for maintaining a route, and unnecessary use of a radio band accompanied with the processing by shortening the delay with respect to the maintenance of a route to a specific node in a radio network where each node frequently accesses a specific node and accesses other nodes less frequently.;SOLUTION: The specific radio node or each radio node transmits a route maintaining packet to each radio node or the specific radio node, respectively, and each node transmits a route maintaining return packet when receiving the route maintaining packet, and the transmission node which has transmitted the route maintaining packet confirms reception of the route maintaining return packet to maintain the route between the specific radio node and each radio node.;COPYRIGHT: (C)2003,JPO
