    • Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc WLANs save power in service discovery phase and provide service availability information quickly and independently from the wireless channels used in the WLAN ad hoc networks. The embodiments perform link-local addressing, Multicast Domain Name Service (DNS), and DNS Service Discovery operations one or more channels of an ad hoc IEEE 802.11 Wireless LAN. A protocol handler in a wireless device is coupled between a standard service discovery protocol module in the device, such as a Zeroconf protocol module or a UPnP protocol module, and at least one internet protocol stack in the device. The Transport, Internet, and Network Interface layers of the IP protocol stack are mapped by the protocol handler to corresponding functions in the standard service discovery protocol module, using a service table for storing information on relationships between available services, wireless devices, and channels on one or more ad hoc wireless networks.

    • An incoming data packet is received, and a rate of change of residual capacity of a portable power supply is determined. From the determined rate of change it is decided to enqueue or drop the incoming data packet. If the decision is to enqueue, the packet is transmitted. If the decision is drop, the packet is deleted without transmitting. Additional factors may be considered in the decision, such as total energy capacity, residual energy capacity, and first and second derivatives of the residual energy capacity. Real time traffic may be treated differently than non real time traffic, and video enhancement layer packets can be weighted to drop more frequently than video base layer packets for the same flow. If used in the network, congestion probe packets are dropped at a rate matched to the rate at which data packets are dropped to give other nodes an accurate view of link quality.
    • 接收到输入的数据分组,并且确定便携式电源的剩余容量的变化率。 从确定的变化率,决定入站或丢弃传入的数据包。 如果决定是入队,则传送包。 如果决定丢弃,则数据包将被删除而不发送。 决策中可以考虑其他因素,例如总能量容量,剩余能量容量以及剩余能量容量的一阶和二阶导数。 实时流量可以被视为不同于非实时流量,并且视频增强层分组可以被加权以相同流量的视频基本层分组的频率下降。 如果在网络中使用,拥塞探测数据包将以与丢弃数据包的速率相匹配的速率丢弃,为其他节点提供链路质量的准确视图。
