ABSTRACT
Moreover, ubiquitous and pervasive computing and Internet of things are some of the causes of the emergence and success of wireless sensor networks (WSNs). While localization is a key aspect of such networks, since sensor’s location is critical in order to provide location-based services or even to interact with the environment, another key aspect is the correct choice of the communication topology and the optimal placement of sensors. As indicated in [1], topology control is an attractive mechanism because it can simultaneously improve energy efficiency and network performance. Topology control can reduce power consumption and channel contention in WSNs by adjusting the transmission power. Once the designer of a WSN identifies the workspace, and the nature and type of services to be provided, he must choose between a cluster and a chain-based topology.
