Mowgli data channel protocol (MDCP)

The Mowgli Data Channel Protocol( MDCP) is a transport protocol for wireless communication that is characterized by a low protocol overhead of only 1 to 3 bytes.

The Mowgli protocol knows two modes of operation: In order to establish an error-free connection, the Mowgli protocol relies in the default mode on the lower protocol layers, which are assumed to be error-free. In the second mode, a more reliable mode, checksums are added to the header.

The scheduled data channels are allocated according to a priority principle, with data packets containing control signals having the highest priority. Acknowledgements are delayed during transmission until multiple acknowledgement fields can be acknowledged with only one acknowledgment( ACK). Flow control is based on a sliding window technique and differs from TCP flow control by a slower acknowledgement. On the receiving side, the data packets are only acknowledged when a certain portion of the transmitted window has been used and enough correct data packets have been received on the receiving side.

A test of the Mowgli protocol compared to TCP/ IP showed that the Mowgli protocol has a better interactive response time behavior.
