Clustering protocol is the most typical hierarchy protocol for wireless sensor networks. It has higher energy efficiency and better network management than traditional flat protocols. However, typical clustering protocols such as LEACH, have some drawbacks: unreasonable distribution of cluster heads, large consumption by the single-hop communication between cluster heads and the sink, and strong dependence...
Wireless sensor networks provide an opportunity to enhance the current equipment diagnosis systems in the process industry, which have been based so far on wired networks. In this paper, we use our experience in the Anshan Iron and Steel Factory, China, as an example to present the issues from the real field of process industry, and our solutions. The challenges are three fold: First, very high reliability...
