SYSTEM AND METHOD OF RELIABLY CARRYING OUT BROADCAST IN AD HOC NETWORK ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a system which reliably carries out broadcast in ad hoc network environment which can reliably broadcast a data packet, by comparing a routing sequence number after a certain node broadcasts a data packet and checking loss propriety of the data packet at the time of broadcast.

SOLUTION: The system has a judgement portion for judging whether it is a router receiving a data packet and transmitting the above-mentioned received data packet to a prescribed mode, a compare portion for comparing a first router sequence number contained in a managed packet sent by the node which has received the above-mentioned data packet and a second routing sequence number stored in own neighbor table, and a controller for determining propriety of retransmission of data packet to the node based on the comparison result of the above-mentioned compare portion.
