Reducing CO2 emissions is an important global environmental issue. Over the recent years, wireless and mobile communications have increasingly become popular with consumers. Today’s typical wireless access network consumes more than 50% of the total power consumption of mobile communications networks. Growth of mobile Internet service usage is expected to drive the growth in wireless access dat...

Telecommunication usage has skyrocketed in recent years and will continue to grow as developing world reaches to wireless as the communication medium of choice. The telecommunications world is only now addressing the significant environmental impact it is creating as well as the incredible cost on power usage. This realization has led to a push towards Green Communications that strives for impr...

Environmental Sensor Networks (ESNs) facilitate the study of fundamental processes and the development of hazard response systems. They have evolved from passive logging systems that require manual downloading, into ‘intelligent’ sensor networks that comprise a network of automatic sensor nodes and communications systems which actively communicate their data to a Sensor Network Server (SNS) whe...

Today, wireless technology forms the communications backbone of many industries—including aviation, transportation, government, and defense. The era of the Next Generation Air Transportation System, (NextGen), is upon us. The Federal Aviation Administration, in collaboration with industry, is deploying NextGen technology on the ground, in the air, at air traffic control facilities and in the co...

The rapid international development of the mobile phone business has led to significant advances in communications engineering. However, the experience base for underwater acoustic communications is much more limited. Meanwhile, the ocean channel has unique characteristics, so that one cannot assume radio modulation schemes are suitable for acoustic communications in the ocean (and vice versa)....

The idea of vehicle-highway communications sufficient to assume driving functions for the driver is not new. Researchers have articulated both its value and feasibility for several decades; and military and vehicle manufacturer test facility developments have proven the concept’s viability. As mounting congestion conflicts with environmental constraints, the Automated Highway System (AHS) promi...

Radical environmental groups and their members have a wide and varied agenda which often encompasses both local and global issues. In their efforts to call attention to environmental problems, communicate with like-minded groups, and mobilize support for their activities, radical environmental organizations also produce an enormous amount of text, which can be used to estimate the complex commu...

introduction: the nursing staff, compared to other professions, have less healthy work environment and always face a lot of job stress. the quality of the relationship between nurses and physicians has a significant impact on nurses. thus, the aim of the present study was to determine the correlation between job stress for nurses with professional communication between nurses and physicians. ma...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...
