I think it is best if it wasn't publicly announced like somehwere on here....that way the government wouldn't have an instant stuff our network button they push right after shutting off the main internet. It is best not to be speaking of such things in public actually then spies would surely discover the plans well in advance to prepare for it. I assume that if there is such a thing then if you are a trustworthy person you will eventually get your hands on it if and when the internet shutoff actually happens.
POPEYE research has produced a multi-layered, scalable, open framework enabling the development of integrated collaborative applications in an infrastructure free environment.
Key features include:
* dynamic peer connection/ disconnection
* multi-hop peers communication
* distributed data sharing and persistency
* dynamic workspace management
* dynamic context management and security
* support for application development
Comparison with Wi-Fi Comparisons and confusion between WiMAX and Wi-Fi are frequent because both are related to wireless connectivity and Internet access. * WiMAX is a long range system, covering many kilometres, that uses licensed or unlicensed spectrum to deliver connection to a network, in most cases the Internet. * Wi-Fi uses unlicensed spectrum to provide access to a local network. * Wi-Fi is more popular in end user devices. * Wi-Fi runs on the Media Access Control's CSMA/CA protocol, which is connectionless and contention based, whereas WiMAX runs a connection-oriented MAC. * WiMAX and Wi-Fi have quite different quality of service (QoS) mechanisms: o WiMAX uses a QoS mechanism based on connections between the base station and the user device. Each connection is based on specific scheduling algorithms. o Wi-Fi uses contention access - all subscriber stations that wish to pass data through a wireless access point (AP) are competing for the AP's attention on a random interrupt basis. This can cause subscriber stations distant from the AP to be repeatedly interrupted by closer stations, greatly reducing their throughput. * Both 802.11 (which includes Wi-Fi) and 802.16 (which includes WiMAX) define Peer-to-Peer (P2P) and ad hoc networks, where an end user communicates to users or servers on another Local Area Network (LAN) using its access point or base station. However, 802.11 supports also direct ad hoc or peer to peer networking between end user devices without an access point while 802.16 end user devices must be in range of the base station. Although Wi-Fi and WiMAX are designed for different situations, they are complementary. WiMAX network operators typically provide a WiMAX Subscriber Unit which connects to the metropolitan WiMAX network and provides Wi-Fi within the home or business for local devices (e.g., Laptops, Wi-Fi Handsets, smartphones) for connectivity. This enables the user to place the WiMAX Subscriber Unit in the best reception area (such as a window), and still be able to use the WiMAX network from any place within their residence.
