Improving throughput and delay is an important challenge in multi-hop wireless sensor networks. In this work, we propose ABC-MC, a simple multi-channel geographic forwarding scheme. ABC-MC is based on ABC which is a lightweight and reliable routing protocol where nodes do not need to set up or maintain routing/neighbor tables. A unique feature of ABC-MC is that it uses a channel prenegotiation mechanism to reduce delay. Another unique feature of ABC-MC is that it takes account of the channel usage information within three hops in channel selection to reduce interference. Experimental results show that ABC-MC outperforms other protocols in terms of the average delay and throughput performance.
