Mobile sensors are often employed for enhancing the sensing coverage and assisting the data gathering in wireless sensor networks. Equipped with unlimited mobility, they are able to move anywhere within the monitored field. Despite the promising simulation (or testbed) result and theoretical conclusion in paper, we have to realize the assumption on unlimited mobility has limitations and is practically...
In this paper, sensor network scenarios are considered where the underlying signals of interest exhibit a degree of sparsity, which means that in an appropriate basis, they can be expressed in terms of a small number of nonzero coefficients. Following the emerging theory of compressive sensing (CS), an overall architecture is considered where the sensors acquire potentially noisy projections of the...
In this paper we introduce our novel concept of sycophant wireless sensors (SWS) which is a static ecto-parasitic clandestine sensor network mounted incognito on a mobile agent using only the agent's mobility without intervention. SWS networks not only communicate with each other through mobile WSN but also cooperate with them to form a global hybrid wireless sensor network (WSN). Our work develops...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
