Wireless network system

Abstract

A system for communication in a wireless backhaul environment having wireless mesh networks connected in part to the Internet comprising a communication topology. The communication topology comprises communication cells each having a relay station and mobile nodes communicating to each other using 802.16j wireless technology wherein the cells are arranged in a grid fabric within the communication topology.

Description

technical field [0001] The present invention relates to a system for communicating in a wireless backhaul environment having a wireless mesh network partially connected to the Internet. Background technique [0002] Internet connections in wireless mesh networks are satisfactory in covering limited communication ranges. The Internet involves addressing schemes for wireless mesh networks. [0003] When the wireless mesh network is not connected to the Internet, the addressing scheme can be flat addressing, so that all nodes do not have to have the same logical Internet Protocol (IP) subnet. Avoiding the use of Network Address Translation (NAT) when a wireless mesh network is connected to the Internet requires nodes to have topologically correct and globally routable IP addresses. [0004] In order to provide multicast routing in a hybrid wireless mesh network, address management becomes even more important. This is because standard multicast routing protocols used in fixed...

Problems solved by technology

[0006] The classic mechanism used for address autoconfiguration in traditional Internet connections cannot be used in wireless mesh networks due to the multi-hop nature of wireless mesh networks
