Inter-vehicle communication (IVC) systems based on wireless ad-hoc networks have the potential to provide increased automotive safety, to achieve smooth traffic flow on the roads, and to improve passenger convenience by providing information and entertainment. However, implementing IVC systems for widespread use also presents a number of technical obstacles. Wireless Technologies in Vehicular Ad Hoc Networks: Present and Future Challenges explores different models for inter-vehicular communication, in which vehicles are equipped with on-board computers that function as nodes in a wireless network. The book covers current theories and applications in physical, medium access, and network layers of IVC systems, exploring inter-vehicle ad-hoc routing protocols and the challenges of predicting vehicular movements, particularly inter-vehicular distance and relative velocity in highly dynamic and varied real-world scenarios.

Generating a new understanding of the past--as well as a vision for the future--this path-breaking volume contains essays written by playwrights, scholars, and critics that analyze African American theatre as it is practiced today. Even as they acknowledge that Black experience is not monolithic, these contributors argue provocatively and persuasively for a Black consciousness that creates a culturally specific theatre. This theatre, rooted in an African mythos, offers ritual rather than realism; it transcends the specifics of social relations, reaching toward revelation. The ritual performance that is intrinsic to Black theatre renews the community; in Paul Carter Harrison's words, it "reveals the Form of Things Unknown" in a way that "binds, cleanses, and heals." Author note: Paul Carter Harrison is playwright in residence at the Theatre Center, Columbia College, Chicago.
