In an electronic marketplace coalition formation allows buyers to enjoy a price discount for each item while combinatorial auction enables buyers to place bids for a bundle of items that are complementary. Coalition formation and combinatorial auction both help to improve the e ciency of a market and have received much attention from economists and computer scientists. But neither in laboratori...

In this paper we discuss the need for resource reservation in the Internet and examine some of the strengths and weaknesses of RSVP, which is currently the most popular of Internet reservation protocols that have been developed. The deficiencies of RSVP motivate our design of a new resource reservation protocol which uses dynamic sender-initiated reservations to achieve a highly bandwidtheffici...

The goal of mobile IP based architecture is to provide seamless mobility with minimized handoff latency, signaling overhead and tunneling cost. There are many research work proposed to support such seamless mobility. Most of the proposals suggest hierarchical arrangement of anchor agents to support minimized handoff latency and signaling cost. But these proposals provide only best-effort servic...

In a system offering on-demand real-time streaming of media files, data striping across an array of disks can improve load balancing, allowing higher disk utilization and increased system throughput. However, it can also cause complete service disruption in the case of a disk failure. Reliability can be improved by adding data redundancy and reserving extra disk bandwidth during normal operatio...

Call dropping is considered more annoying than call blocking in wireless cellular networks. The cost of the classical method of employing guard channels to decrease the call dropping rate is the increase in call blocking rate. Since subscriber mobility changes in time, the number of handoff attempts in each cell is subject to fluctuations, making static assignments (or periodical update) of a g...

| We calculate implied costs for wireless networks and use them for evaluating trade-oos between calls of diierent rates. We model user mobility by assigning probabilities for the departure of calls. We use Fixed Channel Assignment (FCA) with priority for handoos over new call arrivals by reserving a number of channels for handoo calls in all the cells. The performance measures used are new cal...

iii ACKNOWLEDGEMENTS I would like to thank Cem Ersoy for his guidance throughout my PhD study, M. Ufuk Ça˘ glayan for being the model of an academician, Hakan Deliç for his comments on DS-CDMA systems, Abbas Yongaço ˘ glu for his short course on CDMA systems, Emre Çelebi for his valuable discussions and support in Linux, and Ian Anderson for the high spirits. I would also like to thank my wife ...

I thank the referee for reading the paper and for alerting me that I have to phrase things more carefully in order to avoid misreading. Main concerns 1. The entire point is based on misreading the paper. The referee interprets the reservation wage R as relating to the unemployed or people engaged in home production, whereas I have written (I quote the entire paragraph, where the reservation wag...

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract The Resource ReserVation Protocol (RSVP) defines an ...
