A Device-Centric Scheme for Relay Selection in a Dynamic Network Scenario for 5G Communication

摘要: Device-centric architecture is an aspect of fifth generation communication whereby devices/user equipment able to directly communicate with other devices minimal involvement by the base station (BS). However, that are not within their proximity area (relay). In this paper, we propose a device-centric scheme for relay selection in dynamic network scenario. scheme, once communicating have reached maximum distance threshold, they exchange neighbor tables and find common (relay) further communication. addition, new scenarios, where more than one device common. The proposed based on several parameters, including signal-to-noise ratio (SNR), signal-to-interference plus noise ratio, residual battery power, buffer space, reliability; provides reliable efficient current schemes, max–min max–max, assisted; network/BS decides relay, which increases load BS side. selects channel state information or SNR, does provide Our depends less during selection, reduces overhead, A comparison schemes shows our 30% effective each case.
