Device Discovery in D2D Communication: Scenarios and Challenges

Computers, materials & Continua 2023年第4期75卷 1735-1750页

作者： Adeel Iqbal Ali nauman Riaz Hussain Irfan Latif Khan Ali Khaqan Sana Shuja Sung Won Kim COMSATS University Islamabad45550Pakistan Yeungnam University Gyeongsan-si38541Korea

Device to Device (D2D) communication is expected to be anessential part of 5G cellular networks. D2D communication enables closeproximitydevices to establish a direct communication session. D2D communicationoffers many advantages, such as reduced latency, high data rates,range extension, and cellular offloading. The first step to establishing a D2Dsession is device discovery;an efficient device discovery will lead to efficientD2D communication. D2D device further needs to manage its mode of communication,perform resource allocation, manage its interference and mostimportantly control its power to improve the battery life of the device. Thiswork has developed six distinct scenarios in which D2D communication canbe initiated, considering their merits, demerits, limitations, and optimizationparameters. D2D communication procedures for the considered scenarioshave been formulated, based upon the signal flow, containing device discovery,resource allocation, and session teardown. Finally, latency for each scenariohas been evaluated, based on propagation and processing delays.
