Automatic allocation of identifiers in linear wireless sensor networks using link-level processes

Abstract:

Wireless sensor networks, which are used for monitoring large-scale linear structures, are having a significant importance due to its implementation and low cost maintenance. The main challenges that this technology faces are the location and automatic identification of thousands of nodes that are part of a linear large-scale infrastructure, with minimum processing and low power consumption of the nodes. This paper proposes an automatic identification and location mechanism of the nodes that are part of a linear structure using link-level processes and the IEEE 802.15.4 protocol. This mechanism improves the reliability in the allocation process of identifiers without using routing protocols to minimize the number of sent messages, also the computation process is done at the nodes, and therefore it reduces energy consumption. The proposed algorithm is evaluated using a prototype, for which we present initial performance analysis results focusing on delay. The implementation results confirm that with the proposed algorithm we obtain automatic allocations of identifiers.
