    Abstract: A system and method for evaluating at least one communication link between a transmitting node and a receiving node in a communications network, such as a wireless ad-hoc communications network in accordance with the 802.11 standard. The system and method perform the operation of assigning respective link quality values to the respective communication links based on a transmit power level (TPL) value at which the respective data packets were transmitted by the transmitting node over the respective links, a received sensitivity (RS) value of the receiving node receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network for each respective link. The system and method can examine a content of a data packet being sent between the two nodes to determine the TPL, and can receive the RSSI value from a physical layer of the communications network. Accordingly, the system and method can determine which link that additional data packets are to be sent by the transmitting node to the receiving node via the communication link based on the link quality values. Specifically, the link having the highest link quality value is selected.

    Abstract: A method for calculating service redundancy of a wireless network is provided. The method comprises determining one or more of a plurality of routes through which a node can communicate to reach a destination. A routing metric is calculated for each of the plurality of routes. Using the calculated routing metrics a route having a best routing metric is identified as a best route to the destination. Service redundancy for each node within the wireless network is calculated using a sum of weighted ratios of the best routing metric to at least one alternate routing metric.

    Abstract: A system and method for locating and using multiple routes to transmit sub-packets of data from a source node to a destination node in an ad-hoc network, thus preventing intermediate nodes in any one transmission path from intercepting a useful amount of information. The system and method routes communications between a source node and a destination node via multiple routes, selected in a random fashion. Further protection is achieved by breaking data packets into sub-packets requiring reassembly at the destination node.

    Abstract: An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits/hz/km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.
