“…To the best of our knowledge, any previous chain-based network [4][5][6][7][8][9][10][11] does not consider the breakdown of the chain, although the chain can be frequently broken by the failure of a single tag. While the previous works take account of transmission errors only, CCNP provides a way to overcome the chain-broken problem by allowing each tag to adjust the transmission power dynamically depending on the situation.…”

“…Second, replies from all tags are combined into a single message by a specific data fusion method. Although some existing works [8][9][10] allocate TDMA slots to each tag to guarantee the packet transmission without a collision, this may not much contribute to the reduction of the transmission number.…”

The railway is one of the most important facilities for freight logistics. This paper suggests the use of the container security devices (CSDs), which has been adopted for the marine transportation so far, to enhance the security of railway freight transportation. The proposed protocol, CSD Chain Network Protocol (CCNP), was designed for a chain-form network of CSDs, each of which is attached to a container. In CCNP, unauthorized access to freight is reliably reported to the reader deployed at the locomotive. CCNP also cares about the fairness in energy consumption. In a usual chain network, a tag closer to the reader consumes more energy since it ought to forward packets coming from rear tags as well. However, in CCNP, the tag energy consumption for packet forwarding is always the same regardless of the position in a chain owing to an efficient data fusion scheme. In our simulation using QualNet, CCNP reduces the number of disconnections between tags by 59.5% as compared to general chain networks. The energy consumption also decreases by 91.3% of other networks not using an aggregation method.
