Public Safety Networks: Enabling Mobility for Critical Communications

چکیده
Long Term Evolution is becoming the technology reference for 4G cellular networks, as it is increasingly adopted by all major operators all over the world. Currently, LTE is rising to the challenge of addressing several issues (e.g. cellular networks’ capacity crunch, ultra-high bandwidth, ultra-low latency, massive numbers of connections, super-fast mobility, diverse-spectrum access) that speed up the pace towards 5G. Moreover, LTE is expected to be an important part of the 5G solution for future networks and also play an essential role in advancing Public Safety (PS) communications. In US, LTE has been chosen up as the next appropriate communication technology to support public-safety and it is likely to be the same in EU. Moreover, several vendors (e.g. Ericsson, Nokia-Alcatel, Huawei, Cisco) are now starting to propose LTE-based public-safety solutions and some of them have been put to real field experimentation.

Routing protocols for inter-vehicular networks: A comparative study in high-mobility and large obstacles environments
An ad hoc network is composed of mobile nodes without the presence of a fixed infrastructure. Communications among nodes are accomplished by forwarding data packets for each other, on a hop-by-hop basis along the current connection to the destination node. In particular, vehicle-to-vehicle communications have been studied, in recent years, to improve driver safety. As more of such applications ...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. In VANET, nodes which are vehicles can move safety with high speed and must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be circulated to inform all other vehicles. Vehicu...

After the tragic bombing at the Boston marathon, Boston’s cellular networks instantly filled with calls. One company spokeswoman had to publicly plead with its customers “to use text or email to free up voice capacity for public safety officials at the scene." In other words, this nation allocates resources that are critical for emergency response through use of plaintive press releases. U.S. p...
