摘要： An apparatus and methods are disclosed that enable a non-multi-hop wireless terminal (i.e., a wireless terminal that has not been programmed to participate in multi-hop ad-hoc wireless networks) to in fact participate in a multi-hop ad-hoc wireless network, without any changes to the non-multi-hop terminal's software or hardware. In the illustrative embodiment, a wireless terminal T that already belongs to a multi-hop ad-hoc wireless network is assigned to a non-multi-hop wireless terminal W, and a signal is transmitted to terminal W that induces terminal W to use terminal T as a relay for transmitting messages. The assignment of multi-hop-capable terminals in the network to non-multi-hop terminals can be based on a variety of factors, such as signal strengths and the geo-locations of terminals.

摘要： A method and apparatus are disclosed for estimating the location of a wireless terminal across multiple building floors. The illustrative embodiment determines the floor where the wireless terminal is presently located by using a majority logic-based heuristic. A plurality of signal monitors measure signals from the wireless terminal and provide those signal strength measurements to a location estimation server. Alternatively, the wireless terminal measures signals that are transmitted by a plurality of transmitting signal devices and provides those signal strength measurements to a location estimation server. The location estimation server determines the floor of the wireless terminal in accordance with the illustrative embodiment of the present invention.

摘要： A method and apparatus are disclosed for redirecting traffic associated with an application so that the traffic advantageously traverses (or “hairpins”) through an application-layer gateway. Because the present invention advantageously redirects traffic without any participation by routers, no changes to or replacement of routers in a network is required. The illustrative embodiment is disclosed in the context of Internet telephony, but is also applicable to other kinds of applications and types of communication (e.g., Internet Protocol Television [IPTV], instant messaging [IM], videoconferencing, etc.)

摘要： An apparatus and methods are disclosed that enable load-balancing of routes in ad-hoc wireless networks. In accordance with the illustrative embodiment, when a candidate intermediate node receives a routing-protocol message, the node waits before it transmits a message in response to the received message, where the amount of time that the node waits is based on the value of a load metric at the node and is independent of any other nodes in the network. As a result, a node that has a larger load will wait longer to transmit its routing-protocol message, and consequently, it is less likely that this node will be selected for inclusion in the new route. The techniques of the illustrative embodiment are applicable to both proactive and on-demand routing protocols, and are also applicable to other kinds of networks.
摘要翻译：公开了一种能够对ad-hoc无线网络中的路由进行负载平衡的装置和方法。根据说明性实施例，当候选中间节点接收到路由协议消息时，节点在响应于接收到的消息发送消息之前等待，其中节点等待的时间量基于a的值节点处的负载度量，并且与网络中的任何其他节点无关。因此，具有较大负载的节点将等待更长时间来传送其路由协议消息，因此不太可能选择该节点包含在新路由中。说明性实施例的技术可应用于主动和按需路由协议两者，并且也适用于其他种类的网络。

摘要： A method and an apparatus are disclosed that provide a privilege-granting technique for enabling a service-providing domain to grant a privilege to a requesting user in a service-requesting domain. A request handler in the service-providing domain, which comprises one or more service-associated resources, receives a user request to use a service and requests a token from a privilege-granting server, in accordance with the illustrative embodiment of the present invention. Upon receiving the token that specifies a granted privilege from the privilege-granting server, the request handler extends the privilege to the requesting user. Alternatively, the request handler can request a plurality of tokens in advance from the privilege-granting server; after receiving the tokens, the request handler extends a privilege to each requesting user as the handler receives requests to use one or more services.

摘要： A method is disclosed that enables mitigating at least some of the problems caused by a packet attack. When a first Internet Protocol (IP)-capable device is subjected to a packet attack, it indicates periodically to a second IP-capable device that certain communications with the first device are to be suspended. The periodic transmitting of the indication is performed at a slower rate than the keep-alive mechanism that is normally used to detect loss of connectivity. When the second device receives the transmitted indication, it refrains from transmitting keep-alive messages to the first device for a predetermined interval. Meanwhile, the first device also refrains from transmitting keep-alive messages to the second device for a similar interval. In transmitting the suspend indication, the illustrative embodiment seeks to prevent pairs of communicating devices that are experiencing packet attacks from continuing their operation under the erroneous assumption that each device is unavailable.
摘要翻译：公开了一种能够减轻由分组攻击引起的至少一些问题的方法。当第一个基于互联网协议（IP）的设备遭受分组攻击时，它周期性地向第二个具有IP能力的设备指示与第一设备的某些通信将被暂停。指示的周期性发送以比通常用于检测连通性损失的保持活动机制更慢的速率执行。当第二设备接收到发送的指示时，它不阻止向预定间隔向第一设备发送保持活动消息。同时，第一设备也禁止以类似间隔向第二设备发送保持活动消息。在发送挂起指示时，说明性实施例旨在防止正在经历分组攻击的通信设备的对在每个设备不可用的错误假设下继续其操作。
