Laser scanners are optical measuring systems based on laser light transmission. Terrestrial laser scanning is a new and efficient method for digitizing large object s and is used in surveys, which provides ways to acquire complex geometric data from buildings, machines, and objects.Terrestrial laser scanners provide a fast and accurate method of topographical surveying, giving deliverables such as spatial cloud data, DEM, DTM, contour maps and the raw data for databases and technical analysis. It is a ground-based technique to measure the position and dimension of objects in the three dimensional space. It provides benefits such as reduced costs,reduced waste, re-work, increased efficiencies, faster project completion times, improved information flow, improved decision making, and enhanced quality control.

A realization of new communication media which realizes transmission of haptic information between distant places is required. Bilateral control system is an effective technique which can share tactile sensation between two systems. However the performance of the bilateral control tends to destabilize and the haptic information deteriorates under communication delay because haptic information has the bilateral informational flow property. Therefore, this paper proposes a novel method to realize simultaneity in bilateral control system under communication delay. The proposed control system is designed to realize the control goal equations for bilateral control regardless of the delay time and is designed symmetrically. Buffering the force information of the own system solves the interference between the modal space caused by the communication delay. The whole control system is stabilized by using the phase lag compensator which has the equivalent meaning of acceleration response feedback with high pass filter. The validity of the proposed method is confirmed by experiments.

The information and communications technology (ICT) field is undergoing a period of tremendous and rapid change. As ICT develops more rapidly, the United States Air Force needs to remain responsive and adaptive to maintain military advantages. The need to integrate ICT developments sooner than our adversaries prompted an assessment of guidelines evaluating how well the AF is doctrinally positioned from a Command and Control perspective to support integration of emerging ICT. A Delphi Study was commissioned by the 689th CCW to forecast the future of mobile Information and Communication Technology (ICT) in austere environments.

A distributed engine control system (DECS) offering flexibility and scalability is envisioned for the next generation of propulsion controls. Perhaps the most touted benefit of a DECS is the potential to reduce the amount of harnessing which connects throughout the engine. Such a system is comprised of several network sections incorporating control nodes or data concentrators (DCs). These DCs contain control logic to perform control function computations and are connected to the full authority digital engine control (FADEC) via a high-speed data communication bus. A novel approach for analyzing and evaluating three topologies; ring, star, and bus in the context of a relevant military engine was described. In this study, the algorithm uses a particle swarm optimization process to evolve solutions to a multi-objective optimization problem. The results of this study indicate there is potential for large wire length savings in a distributed control architecture.

This chapter presents selective gossip which is an algorithm that applies the idea of iterative information exchange to vectors of data. Instead of communicating the entire vector and wasting network resources, our method adaptively focuses communication on the most significant entries of the vector. We prove that nodes running selective gossip asymptotically reach consensus on these significant entries, and they simultaneously reach an agreement on the indices of entries which are insignificant. The results demonstrate that selective gossip provides significant communication savings in terms of the number of scalars transmitted. In the second part of the chapter we propose a distributed particle filter employing selective gossip. We show that distributed particle filters employing selective gossip provide comparable results to the centralized bootstrap particle filter while decreasing the communication overhead compared to using randomized gossip to distribute the filter computations.

The next frontier in sensor networks is sensing the human society. Human interaction, with technology and within mobile communities provides enormous opportunities to provide new paradigms of user communication. Traditionally, communication in computer networks has focused on delivering messages to machine identities. Each host is uniquely addressed, and network protocols aim to find routes to a given machine identity efficiently. While this framework has been proven successful in the past, it is questionable whether it will be sufficient in the era of social networking and mobility. As we envision the emergence of mobile terminals tightly coupled with their users and thus reflect the behavior and preferences of the users, it is beneficial to consider an alternative (and complementary) framework: Could user behavior be collected and summarized as a representation of the user's interest, and be leveraged as a way to guide message delivery? In this chapter, we elaborate on this possibility, discussing user behavior trace collection, representation, and pioneering works on behavior-aware mobile network protocols. This proposed new framework is to be used mainly as an alternative of the IP (routing) layer in the Internet today and provides a new mechanism for network message routing. However, as opposed to the current routing schemes (e.g., IP) which address each host with a unique ID, in this new framework it is the behavior descriptors of the hosts, not its identities, to be used as the target for a message. Therefore, in behavior-aware routing protocols, messages are destined to a behavior descriptor and it is moved across the network based on comparisons of behavior descriptor of intermediate nodes to the target behavior. Note that a behavior descriptor can map to many potential recipients, or none. This chapter provides a survey of important research work on behavior-aware routing. In this chapter, we motivate and introduce the new paradigm in Sect. 1. In Sect. 2, we introduce the goal of behavior-aware routing and its challenges. We then introduce a framework, namely TRACE, to discuss the steps involved in the design of social behavior-aware routing. We also give examples from the literature to explain what each step involves. The most important task in this paradigm is to summarize and represent node behavior in a succinct form, in such a way that the new representation can be used in place of node identities (e.g., addresses) for routing. We then provide examples for various behavior-aware routing protocols from the literature in Sect. 3. Important research topics in this area for further study are discussed in Sect. 4. Section 5 concludes the chapter.

As discussed in the previous chapter, Low Power Communication is the key to realization of a low power sensor node. Since sensor nodes require only low data rate communication, it might sound intuitively clear that they should also naturally be low power. After all, if a node does less work, it should also consume lesser power. But somehow this doesn't seem to fit the behavior for low data rate communication, short range radios. If we look at existing radio designs at various data rates and ranges, we see that the design space occupied is very wide. There are designs that operate at very high (～100 Mbps) data rates and designs that operate at low data rates (～100 Kbps). There are designs that take wall supply, consuming a few watts of power, while some work on batteries. If one looks at energy per bit requirements of these designs, while some designs operate at hundreds of nJ/bit, some other designs exist consuming only 0.1 nJ/bit (Fig. 2.1). Now if we plot the range over these designs and examine how they should scale according to the energy/ bit requirements we should see radios working at low data rates while consuming few microwatts of power, as required by sensor networks. These designs do not exist. The reasons there aren't any designs in this space requires us to consider the consequences of scaling traditional design as we go for lower and lower data rate. Since Shannon's law governs the limit on the energy efficiency of radio communication and link margin vis-a-vis the channel capacity, it makes sense to have a closer look at it and then see what constraints typical radio architectures have that prevent power from scaling in low data rate applications.
