This paper studies the price-quoting strategies used by a tier-two supplier, whose tier-one customers compete for an OEM’s indivisible contract. At most one of the tier-two supplier’s quotes will ultimately result in downstream contracting and hence produce revenue for her. We characterize the tier-two supplier’s optimal price-quoting strategies and show that she will use one of two possible ty...

1— In self-organized mobile networks, the need to know identifiers in order to establish connections is a burden to the users. The focus can be shifted from the nodes to the services they provide. Service discovery enables simple browsing and location of services available in the network and can offer support to the creation and advertisement of user communities. Although solutions exists for a...

Multi-tier Wireless ATM Network Bora A. Akyol Donald C. Cox BBN Stanford University 10 Moulton Street Department of Electrical Engineering Cambridge, MA 02138 Stanford, CA 94305 Abstract| This paper presents a new protocol for controlling access to the shared radio medium in a multi-tier wireless ATM network. A multi-tier Wireless ATM network provides seamless connectivity to the users in multi...

Persistent scatterer (PS) interferometry (PSI) has the ability to achieve submeter-scale digital elevation model and millimeter-scale deformation. However, it is difficult maintain good performance under long baseline large phase gradient. In this article, we develop a network optimized ridge estimator for two-tier PSI. Such method can increase parameter estimation robustness spatial continuity...
