Abstract – Hwang and Li proposed the first remote user authentication scheme using smart cards to solve the problems of Lamport scheme. Unfortunately, Hwang and Li’s scheme has some security weaknesses. First, Chan- Chang, Shen- Lin- Hwang and then
This paper proposes a new Automatic Repeat Request (ARQ) scheme for reliable broadcasting in distributed wireless LANs. Unlike traditional ARQ schemes for reliable broadcasting, the proposed scheme is highly efficient in its ARQ control information
Abstract—We propose a velocity-based bicasting handover scheme to efficiently utilize backhaul network resources in Fourth-generation (4G) mobile systems. The conventional bicasting scheme makes all potential target base stations hold the user data,
In this contribution, we propose a TFCI coding scheme for 1.28 Mcps TDD option when 8PSK modulation is used. In 1.28 Mcps TDD option, when QPSK modulation is used, the current TFCI coding scheme is the same as that of 3.84 Mcps TDD option; depending
