The innovation in wireless technology is to support in the areas of Intelligent Transport System (ITS). Wireless technology can be used in Vehicle-to-Vehicle and vehicle-to-infrastructure in transport applications. ZigBee is the key protocol for sensor network applications because of the long battery life, low-cost for installation, eases maintenance and small footprint. ZigBee enables mesh networking...
This paper presents CARNIVORE, a system for in-situ, yet unobtrusive monitoring of cryptic, difficult-to-catch/observe wildlife in their natural habitat. CARNIVORE consists of a network of mobile and static nodes that have sensing, processing, storage, and wireless communication capabilities. One of CARNIVORE'S notable novel features is its robustness to intermittent node connectivity since, depending...
With the rapid development of computer communication and web technology, especially the widely application of wireless sensor and embedded technology, Wireless Sensor Networks (WSNs) have been paid great attention in industry field and our daily life. WSNs based on ARM7TDMI-S CPU and ZigBee device has merit of rapid and simple in networking, node movable in application, abundant information in acquisition,...
Recent advances in wireless technology have led to the proliferation of wireless devices, ranging from wireless LAN to cellular phones. There has been, and will be, an increase in not only the number of wireless services, but also the number of types of wireless services, and greater demand for mobility, portability, and integrated services. For wireless success to continue, technologies must support...
The availability of secret keys is a precondition for the use of many security solutions and protocols. However, securely assigning such keys to nodes is a challenging task in the context of wireless sensor networks. In this paper we present a novel solution for a secure key assignment in wireless sensor networks that can be used during the initial configuration of nodes or for an ad-hoc key assignment...
An important challenge in mobile sensor networks is to enable energy-efficient communication over a diversity of distances while being robust to wireless effects caused by node mobility. In this paper, we argue that the pairing of two complementary radios with heterogeneous range characteristics enables greater range diversity at lower energy cost than a single radio. We make three contributions towards...
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...
