TCP Performance in Wireless multi-hop Networks

Introduction

Early research showed TCP suffers poor Performance in wireless networks because of packet losses and corruption caused by wireless inducted errors Further studies searched for mechanism to improve TCP performance in cellular wireless systems Other researches investigated other network problems that negativly affect TCP performance, such as bandwidth asymmetry and large round trip times, which are prevalent in satelite networks During the presentaition we adress another network charackteristic that impacts TCP performance, which is common in mobile ad hoc networks: link failures due to mobility First present performance analysis of standart TCP over mobile ad hoc networks Then present analysis of the use of explicit notification techniques to counter the affects of link failures
