The artificial cobweb routing of tree-type physical topology of LVPLC is analyzed
in this paper. The artificial cobweb routing algorithm is further improved. The
conclusions are as follows:
1) The novel routing algorithm solves the problem of part of nodes can't
access the PLC system caused by the limited data connectivity and improve the
reliability of communication. Although the establishing of routing require some
time, the principle of route maintenance keeps the process of route maintenance
after networking is simple, ecient and easy to operate. But the process of
algorithm initialization need some time, which should be improved in later work.
2) Routing reconstruction algorithm can solve the problems of bad nodes
in local network, avoid all the nodes involved in the process of routing recon-
struction, improve the time eciency of communication system and enhance the
anti-destroying ability of PLC system effectively.
3) Each node sends data according to strict time series, hence it reduces the
channel collision rate sharply and improves the channel utilization. Therefore, it
ensures the communication reliability of cobweb from the aspect of effectiveness.
All these results prove that the cobweb structure is feasibility in routing method
to improve the reliability of LVPLC and can guarantee the QoS of PLC. This
routing algorithm may also provide a novel routing method for other network
such as wireless sensor network, ad hoc network etc.
