    The issues related to mobile IP implementation are being investigated for a variety of commercial and DoD applications. Specific issues include the effects of link asymmetry, unidirectional link routing (UDLR), and mobile platform network mobility. We set up a "TCP and Mobile IP Network Testbed for Mobile Platforms," which enables us to simulate various network topologies such as asymmetric links,... View full abstract»

    We address several QoS routing problems in wireless ad hoc networks. Due to mobility or limited battery power, a link between two nodes can last for a certain period, which is represented by a life parameter. On the other hand, each link has cost parameters which can represent the delay of this link, the transmission power needed to support this link and so on. The life of a path is the shortest l...

    In a tactical communication network, nodes can be stationary, movable or fully mobile. Data traffic going to and from these nodes can have full transparency throughout the network and they should not depend on the underlying topology forming the transport layer. The Swedish Armed Forces has a large-scale network based on a stable infrastructure utilizing moveable microwave links. This network has ... View full abstract»

    The performance of a noncoherent, serial acquisition technique is evaluated for direct-sequence spread-spectrum packet communications. The output of a filter matched to the packet's preamble is sampled at twice the chip rate during acquisition, and each sample is compared with a fixed acquisition threshold. The effect of sample-timing error on the acquisition performance is examined. View full abstract»

    It is well-known that conventional double-sideband (DSB) transmission is not bandwidth-efficient; and historically, in applications where bandwidth is relatively scarce, analog single-sideband (SSB) and vestigial-sideband (VSB) techniques have been used. Previously, high-definition television (HDTV) has opted to send its images digitally-employing multi-level, amplitude-shift-keyed, VSB transmissi... View full abstract»

    This paper considers iterative demodulation and decoding of the concatenation of a convolutional code and partial response Gaussian-filtered minimum-shift keying (GMSK) modulation. Demodulation is simplified through the approximation of GMSK as a superposition of pulse amplitude modulated signals, leading to a representation as the inner convolutional code of a serially concatenated convolutional ...

    In this paper, we propose a new weighted round robin (WRR) algorithm for fixed length packets. Two well-known algorithms in the scheduling discipline are the packet-by-packet generalized processor sharing (PGPS) and the worst-case fair weighted fair queueing (WF2Q). The WF2Q has been suggested to eliminate the PGPS burstiness problem exhibited in a flow packet departure proce... View full abstract»

    Deploying a static IP overlay of a mobile ATM network invariably results in poor routing of IP packets: mobile ATM isolates all aspects of mobility from the IP layer by maintaining IP adjacencies regardless of the mobile network's current location. This paper describes a novel technique based on PNNI augmented routing (PAR) that allows mobile routers to adapt and optimize their routing adjacencies... View full abstract»

    In this paper, we propose a novel approach to enhance data confidentiality when transmitting across insecure networks. The idea is to take advantage of the distributed nature of networks such as Internet or wireless networks and combine the secret sharing scheme and multipath routing.

    Active networks allow customized processing of data traffic within the network which can be used by applications to improve the quality of their sessions. To simplify the development of active applications in a heterogeneous environment, we propose "active pipes" as a programming abstraction to specify transmission and processing requirements. We describe how an active pipe can be mapped onto netw... View full abstract»

    Since existing acquisition systems have a fixed threshold value, they are unable to adapt to varying mobile communication environments. This results in a high false-alarm rate or low detection probability. In this paper, an adaptive hybrid acquisition system that adopts an antenna diversity technique and the cell-averaging constant false alarm rate (CA-CFAR) algorithm is presented to acquire a pse...

    A new and reliable MAC protocol is proposed to reduce the number of control handshake messages, such as RTS (Request-To-Send) and CTS (Clear-To-Send), incurred prior to data transmission in ad hoc wireless networks. Such a handshake is currently being used in the IEEE 802.11 DFWMAC (Distributed Foundation Wireless MAC) protocol. Our protocol is power efficient since fewer control messages are bein...
