We propose a sensor positioning scheme for a wireless sensor network consisting of beacons as well as collaborative anchors (CA) to help sensors within a prescribed service area to locate themselves. We assume a robust performance is achieved in the sense that a prescribed location accuracy requirement is fulfilled within the service area. Under the assumption that the time-of-arrival and location...
An emergent modeling approach is proposed to the study of E-service workflow, which is inspired by the characteristics of emergence and self-evolution in biological neuroendocrine-immune network. E-services are represented by autonomous bio-entities (mobile agents with biological operation), The E-service workflow composition is achieved by the evolutionary community of the bio-entities. By understanding...
Coverage control is a basic research problem in wireless sensor networks (WSNs). This paper proposes a distance optimization based coverage control algorithm, which utilizes ant colony algorithm to place sensor nodes to an appropriate position and optimize the moving path of mobile sensor nodes. The proposed algorithm not only guarantees the biggest coverage of wireless sensor networks, but also reduces...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
