A Survey on Cooperative Communication in Wireless Networks

Abstract

Abstract-Cooperative communication in wireless networkshas become more and more attractive recently since it could mitigate the particularly severe channel impairments arising from multipath propagation. Here the greater benefits gained by exploiting spatial diversity in the channel. In this paper, an overview on cooperative communication in wireless networks is presented. We inscribe the benefits of cooperative transmission than traditional non -cooperative communication. Practical issues and challenges in cooperative communication are identified. In particular, we present a study on the advantages, applications and different routing strategies for cooperative mesh networks, Ad hoc networks and wireless sensor networks.

A comparative study of full‐duplex relaying schemes for low latency applications

“…1,2 However, in regards to the end-to-end latency, this requirement has a significant impact on the system quality and the fluidity of communications, and it is influenced by different features upon the transmission, we mention in particular, the propagation delay as well as the relay delay processing. To address this issue, upon a spectrally-efficient transmission, this paper investigates the performance of a 1 full-dulpex relay system and considers for that purpose, 2 basic relaying schemes, namely, the symbol-by-symbol transmission, i.e., amplifyand-forward and the block-by-block transmission, i.e., selective decode-andforward.…”

Such type of data belongs to real time's domain, where schedulability is one of the main characteristics of this domain, which means its propensity to respect the expected time constraints.…”

A Novel Handoff Necessity Estimation Approach Based on Travelling Distance

“…There is a one more kind of handover, known as group handover was produced at the time trains, buses or other vehicles are on the way. The group handovers or cooperative handovers are used to balance the load through the utilization of cooperative communication [4].…”

A Comprehensive Survey on Cooperative Relaying in Industrial Wireless Sensor Network

“…The cooperative communications has the ability to mitigate the effect of fading in wireless networks via antenna diversity, however it resolves the difficulties of installing multiple antennas on small communication terminals [2]. In cooperative communication, multiple user mutually share and coordinate their resources to improve the quality of data transmission where multiple source node can act as relays for each other [12]. Thus the number of relay nodes assigned are used to help the source in forwarding its data to the desired destination, hence forming a virtual antenna array.…”
