Enhanced adaptive SNMP for mobile devices
面向移动设备的增强型自适应SNMP协议

Combining the standard C/S model and the new adaptive trap scheme, a novel adaptive SNMP for mobile devices was proposed. This new method divided all trap messages into three categories and merged some non-emergent trap messages into a larger one before sending. On the other hand, the very important trap message was sent by agents and acknowledged by NMS to make sure a reliable delivery. According to the trap packet generated procedure and the emergent level, different trap levels used various reporting schemes which efficiently occupy the limited bandwidth of wireless channels. The performance analysis shows that the enhanced scheme of classifying and combining trap packets decreases the utilities of link bandwidth without increasing delay of dealing. The reliability of important trap delivery is increased.
