This chapter discusses the challenges, state of the art, and future trends in context aware environments (infrastructure and services) for the Internet of Things, which is defined as a world-wide network of uniquely identified self-organized and intelligent things. Intelligence means primarily the capability of things to be aware of the context in which they operate (time, geographic location, geographic dimension, situation, etc.) and to inter-cooperate with other things in the environment. The Chapter is structured in three sections. The first section, which frames the issues discussed in the rest of the chapter, is a systematic presentation of the most relevant concepts and aspects related to the infrastructure and services for the Internet of Things. The second section presents relevant research works in the infrastructure, and up to date solutions and results regarding the infrastructure and services. The third section presents future trends and research directions in the domain.

This paper describes the development of the Rutgers Interactive Lane Closure Application (RILCA), an interactive computer tool to plan lane closures for work zones. This tool provides traffic engineers with a computerized and easy-to-use lane closure application, along with other useful features. RILCA was developed with the Arc View geographic information system (CIS) software package as the main development environment. Arc View displays the interactive CIS map of the New Jersey Turnpike, Garden State Parkway, and other major freeways in New Jersey and its surrounding network. RILCA provides various analysis and visualization options to plan lane closures interactively, obtain traffic volume information, and conduct accident queries. RILCA was tested successfully, and New Jersey Department of Transportation (DOT) and New Jersey Turnpike Authority engineers now use it with all of the features presented in this paper. RILCA received an annual implementation award from the New Jersey DOT in 2009. The award recognized RILCA's usefulness and potential to improve the efficiency of traffic operations as a practical decision-support tool for lane closure decisions.

This report presents the state-level results of a spatial analysis effort calculating energy technical potential, reported in square kilometers of available land, megawatts of capacity, and gigawatt-hours of generation, for six different renewable technologies. For this analysis, the system specific power density (or equivalent), efficiency (capacity factor), and land-use constraints were identified for each technology using independent research, published research, and professional contacts. This report also presents technical potential findings from previous reports.

The Maumee River watershed is the largest drainage basin that discharges into the Great Lakes. Although the watershed is largely a rural landscape, several major urban-industrial cities, including Fort Wayne and Toledo are located along the river. Many water quality concerns are present, especially non-point rural runoff that contributes significant amounts of sediment into the Maumee River. There is an important need to collect, organize and assess the available information on the watershed conditions and to better determine the status of the changes with land uses, crop rotation, and implementation of conservation tillage practices within this watershed. A partnership between the University of Toledo and US Department of Agriculture NRCS lead to several GIS and remote sensing products including annual land cover and crop rotations via remote sensing techniques, establishment of a Maumee Watershed Project Area GIS database, and providing educational and informational outreach with other project partners, resource managers, and the general public.

This project presents five tools that were created for a geographical information system to estimate Annual Average Daily Traffic using linear regression. Three of the tools can be used to prepare spatial data for linear regression. One tool can be used to calculate a connectivity importance index for the streets of a city. The main tool can be used to conduct linear regression to estimate Annual Average Daily Traffic. The tools were created for ArcGIS 10 using open-source python scripting.

Forest information collection plays an important role in the process of building modern forestry. This paper proposes a monitoring system-Sensing Forest System, based on the Internet of Things, 3G and 3D GIS, to make up for the shortcomings of traditional monitoring methods. Key issues, such as system architecture, design of wireless multimedia sensor nodes and data transfer process in the network, have been studied and presented, for obtaining real-time comprehensive forestry information, accurately, automatically and remotely, to lay foundations for applications of the Internet of Things in forestry.

State Departments of Transportation, including the Texas Department of Transportation (TxDOT), have long been moving towards the development and implementation of pavement management systems that would enable monitoring of the performance of their roadways, as well as assist transportation officials with maintenance budget allocation and planning decisions. Various past attempts focused on using the available performance databases as well as state-of-the-art concepts for the development of such systems. The unique characteristics of the state of Texas, the most predominant of which is the vast size of the managed pavement network--79,696 centerline miles of highways including 49,829 bridges--have made some of the decision support models and/or algorithms a challenge to implement. This report presents a new approach to the development of such a decision-support system with its focus on maintenance management for TxDOT. The new system is web-based and provides functional capabilities that allow transportation officials and engineers to make informed decisions regarding their budget planning and budget allocation for pavement maintenance management, fully utilizing available historical data. The developed system has successfully supported some of the TxDOT Districts in the development of their 4-year pavement management plans.

Exploring new applications and services for mobile environments has generated considerable excitement among both industries and academics. In this paper we propose a context-aware recommender system that accommodates user's needs with location-dependent multimedia information available in a mobile environment related to an indoor scenario. Specifically, we propose a recommender system for the planning of browsing activities that are based on objects features, users' behaviours and on the current context the state of which is captured by apposite sensor networks. We present the features of such a system and we discuss the proposed approach.
