The Average Throughput (bits/sec): the normal throughput is the normal of bits number of remedied messages that convey over a channel of correspondence for every time unit over second [6]. The normal throughput condition can be determined by utilizing the general recipe as follow: 𝑏𝑖𝑡 (1) 𝑃𝑎𝑐𝑘𝑒𝑡 𝑆𝑖𝑧𝑒 ( ) 𝑠𝑒𝑐 The size of the packet is the size of served data in framing n between the initial time, tn, of framing n and the time of initial, tn+1, of the next framing n + 1 [6]. 𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑇ℎ𝑟𝑜𝑢𝑔ℎ𝑝𝑢𝑡 = 𝛴

The Average Delay (sec): the arrived at the midpoint of deferral is the End to End time of transmission between the base station and portable endorser station. It speaks to what extent it takes to transmit a piece from the sender hub to the beneficiary hub [6]. Normal postpone condition can be determined to utilize the general equation as follow: 𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑑𝑒𝑙𝑎𝑦 =

𝛴

𝑑𝑒𝑙𝑖𝑣𝑒𝑟𝑦 𝑡𝑖𝑚𝑒 − 𝛴 𝛴

𝑎𝑟𝑟𝑖𝑣𝑎𝑙 𝑡𝑖𝑚𝑒

𝑟𝑒𝑐𝑒𝑖𝑣𝑒𝑑 𝑝𝑎𝑐𝑘𝑒𝑡

The Average load (bits/sec): the average load is the bits number being submitted to the WiMAX media get to control layer by its upper layer over second [7][5]. System delay speaks to the time taken by the bundles to make a trip from the sender to the beneficiary that deliberate over seconds [7]. System throughput is the all-out information that arrives at the recipient from the sender. It is the estimation of the information rate or how quickly the information can be sent. The normal units used to gauge throughput in bits every second (bps) or parcels/seconds [8]. Then again, hub insights include: Delay (sec): is the general postponement of the WiMAX organize. Fig. (3) shows the postponement of a WiMAX organize when the deferral has tried in general the WiMAX coordinate with voice property. Fig. (4) shows the general deferral of the WiMAX coordinate with the postponement at BS1. Packet End-to-End Delay(sec): it is the deferral between one endpoint to another endpoint that supports voice application. Fig. (5) shows the endpoint that verified with the parcel to get the outcome and figures the occasions that bundle moved to show up toward the end point[9]. Throughput(sec): the information that arrives at the recipient hub from the sender node[10]. Fig. (6) shows the throughput somewhere in the range of BS1 and MS1 to discover the information that the specialist organization sends to the end user[11][12]. Table. (1) depict the directions of the scopes and longitudes of Istanbul colleges on the earth. These qualities express genuine situations for every college hub and genuine good ways from college to others [12]. These parameters and qualities are referenced in Table I.

This permits us to improve the data rate, transmission over throughput, delay, and load. Table (II) portrays the parameters for every college. Every college has WiMAX arrange detail parameters, for example, cell range (that figure the inclusion territory separation for each base station and endorser in the cell of WiMAX organize) for every hub and every hub has a recurrence that takes a shot at it. Their qualities rely upon the foundation that the system takes a shot at it, for example, Wi-Fi, or WiMAX innovation. Thus, every one of these innovations utilizes a particular component and recurrence that identifies with its sort of innovation. Every cell has a particular separation go inside it to cover. Every one of these cells includes a scope of data transfer capacity (that decides the recurrence) that relies upon balance and coding, reception apparatus gain, transmission power, and different parameters of the WiMAX organize. The regular WiMAX parameters in both base stations and portable supporter stations are transmission strategy OFDMA, sort of tweak and coding, kind of duplexing plan, radio wire gain, transmission power, and multipath channel model. While every college has parameters that are not quite the same as different colleges. Such parameters incorporate the sort of recurrence, data transmission, the inclusion territory for every college and the number of supporters that fluctuate from base hub to other people.
