摘要

隨著科技的發展，行動裝置的普及，以及對多媒體的需求日漸增加，人們對於行動網路的需求也跟著大幅的增加。長程演進技術(Long Term Evolution, LTE)是目前標準的4G無線網路接取技術，而LTE-Advance(LTE-A)則是滿足ITU-R所定義的IMT-Advanced標準，具有在高速移動的情況下達到約100 Mbit/s的速率，在低速移動的情況下高達約1 Gbit/s的速率，在LTE的環境架構下，明確的規範行動裝置(User Equipment, UE)如何透過無訊訊號與LTE核心網路(Evolved Packet Core, EPC)的基地台(Evolved NodeB, eNB)連線並透過無線介面進行資料的傳輸。另外隨著物聯網(Internet of Things, IOT)的逐漸普及，車載網路的需求也逐漸增加，透過車輛之間的行車相關訊息交換，可以有效增加行車安全性，避免事故發生。Device-to-Device(D2D) communication的概念接著在Release 12中被提出，D2D指的是一種可不透過基地台轉送，直接在無線裝置間進行通訊的技術，而LTE的系統被認為是一個能支援Vehicle-to-Vehicle(V2V)的方法，V2V透過共用核心網路中CUE的頻譜資源來進行通訊，會造成使用相同資源的CUE及V2V對彼此造成干擾，因此如何有效地進行資源分配就是一個研究中的重點。本文探討如何在LTE網路中，設計以分組方式為基礎並結合現有演算法的資源分配方式，分析不同分組方式搭配不同演算法在Total Interference及System Capacity的成果，並透過分組概念及演算法特性探討實驗結果的效率。

Long Term Evolution (LTE) is currently the standard 4G wireless network access technology. With the gradual popularization of the Internet of Things (IOT), the demand for Vehicular ad hoc networks (VANETs) is gradually increasing. Our scenario is in the Multiple traffic lanes in the same direction of a base station 's signal range. Vehicles need to exchange traffic data between each other. Assuming that the number of vehicles is greater than the number of CUEs, delays and loads of a base station can be reduced by grouping the vehicles and transmitting them through Vehicle-to-Vehicle (V2V).
Device-to-Device(D2D) refers to a technology that can directly communicate between wireless devices without transmitting through a base station, and the LTE system is considered as a method that can support V2V. V2V communication passes through reusing the CUE's spectrum resource in the core network which will cause CUE and V2V using the same resources to interfere with each other. Therefore, how to effectively allocate spectrum resources is a key point in the research.
This article discusses how to design a group-based approach in LTE networks and combine the resource allocation algorithms of existing algorithms to analyze the results of different grouping method and different resource allocation algorithms in Total interference and System Capacity. And through the concept of grouping method and resource allocation algorithm features to explore the efficiency of the experimental results.
