Abstract
The mobile ad-hoc network includes a plurality of mobile nodes connected together by a plurality of wireless communication links. The method and system for monitoring link quality includes, at each node, recording transmission information for transmissions on links to neighboring nodes, calculating a packet error rate for each of the links to the neighboring nodes based upon the recorded transmission information, and determining link quality for each of the links to the neighboring nodes based upon the calculated packet error rate. The transmission information preferably includes packet size transmitted data, packet size received data, collision data and/or retry data.
