Bandwidth, power and collision are considered as three important resources in wireless networks. Therefore, how to manage these resources becomes a effect on wireless ad hoc network. These effects are not present in wire line networks, and evaluation of available bandwidth in wireless networks a difficult task. Furthermore, in wireless medium the available resources also vary with the protocol ...

To improve the uplink performance of wireless network for long term evolution (LTE) single carrier frequency division multiple access (SC-FDMA) and orthogonal (OFDMA) are used. Two major concerns these SC-FDMA OFDMA high peak-to-average power ratio (PAPR) efficient subcarrier mapping scheme. This paper presents a comparison under different schemes which includes localized FDMA (LFDMA), distribu...

Broadcast protocols play a vital role in building services and applications for multihop, mobile, wireless ad hoc networks (MANET). This paper describes the design, implementation and evaluation of a new broadcast protocol for a multihop, mobile wireless ad hoc network that provides significantly better performance than the currently existing protocols. In particular, this protocol provides low...

Carrier frequency offset (CFO) is a challenging problem in the uplink of single-carrier division multiple access (SC-FDMA) system. CFOs effect on orthogonality between subcarriers and cause inter-carrier interference (ICI) (MAI). This paper, analyzes impact performance Discrete Sine Transform (DST) SC-FDMA (DST-SC-FDMA) system investigates with different wireless channels, modulation schemes ma...

Abstract The 0–1 mixed integer programming problem of binary offloading on wireless powered mobile edge computing (WP‐MEC) networks requires joint optimization and continuous variables, which is computationally expensive for traditional techniques difficult to solve within the channel coherence time under time‐varying condition. Using machine learning models output variable values also challeng...
