Wireless ad hoc network positioning algorithm based on self-organizing Map and received signal strength Nyein Aye Maung Maung Makoto Kawai Abstract Positioning or localization of wireless ad hoc networks has gained much research attentions for several years. This paper proposes a hybrid positioning algorithm which exploits Received Signal Strength (RSS)-based ranging and Self Organizing Maps (SOM)-based range free localization methods to obtain the tradeoff between cost, power and location accuracy. Distance information from RSS measurement has been utilized in the learning steps of SOM-based localization algorithm to get more accurate location estimates while reducing number of learning steps. Method on RSS uncertainty reduction is also incorporated in the proposed hybrid RSS-SOM algorithm. Results from extensive simulations prove that the hybrid RSS-SOM algorithm outperforms several existing positioning algorithms for all node density, anchor utilization and the number of learning steps. 2012-10-01 http://hdl.handle.net/20.500.12678/0000005215 https://meral.edu.mm/records/5215
