The use of two radios per node increases the energy efficiency of wireless sensor networks. Given that data collection is one of the most important functions in wireless sensor networks, this paper presents and compares two new data collection protocols for wireless sensor networks with two radios, DCTP-A and DCTP-I. DCTP-A builds the collection tree alternating the radio band each node while DCTP-I builds two independent collection trees. The protocols were implemented in TinyOS and evaluated experimentally in a testbed in the physical world using the 900MHz and 2.4GHz radio bands, compared to the state of the art (CTP and CTP-Multi) and to each other, considering the metrics delivery rate, latency, throughput in a saturated network scenario, total number of messages and the cost of maintaining routes. The results show the gain of the protocols for wireless sensor networks with two radios. DCTP-A achieved almost 100% of delivery rate, while DCTP-I achieved up to 90% delivery rate with less number of beacons messages.
