A borrowed address assignment algorithm for ISA100.11a networks based on DAMM algorithm

ISA100.11a has not set a standard agreement about the algorithm which is used to realize address assignment This paper is aimed at the topology of industrial wireless network in ISA100.11a, designed a borrowed address assignment algorithm for access network equipment based on DAMM (Distributed Address Assignment Mechanism) algorithm. This algorithm adopts multi-way tree structure model, completing routing nodes´ default address assignment according to network configuration parameter, on the other hand, setting the weight threshold to realize address borrowing assignment when the routing space is insufficient. The testing results have showed that borrowed address assignment algorithm has a high ratio of addressed nodes and spends low time to forming network compared with DAMM algorithm. So borrowed address assignment algorithm meets the effective use of address source and avoids orphan problem at the same time.
