Abstract AR
في هذا البحث تم بناء شبكة لا سلكية محلية لاستخدامها للدخول إلى الإنترنت من خلا شبكة GPRS الخلوية باستخدام منفذ دخول مربوط إلى مقسم.
تتم إدارة هذه الشبكة من خلال خادم تم برمجته باستخدام نظام التشغيل Linux.
نظرا للإمكانيات المحدودة التي توفره شبكة GPRS مثل العنونة المتغيرة IP.
و لغرض تقليل استخدام حزمة الانترنت تم إضافة خادم Proxy حيث يقوم بخزن الصفحات التي تم استدعاؤها في وقت سابق لغرض الاستخدام اللاحق و زيادة سرعة الحصول على البيانات من قبل المستخدم.
كما أن إضافة مترجم العناوين NAT جعل بالإمكان مشاركة نفس العنوان من قبل أكثر من مستخدم.
نظرا لعدم سرية تبادل البيانات في أوقات مختلفة كان بمعدل 10.9Kps للتحميل 143.3 للإرسال و 376.6Kbps للاستلام.
Abstract EN
In this paper a WLAN network that accesses the Internet through a GPRS network was implemented and tested.
The proposed network is managed by the Linux based server.
Because of the limited facilities of GPRS such as dynamic IP addressing besides to its limited bandwidth a number of techniques are implemented to overcome these limitations.
Dynamic Host Configuration Protocol (DHCP) server was added to provide a single central control for all TCP / IP resources.
Squid Proxy was added to provide caching of the redundant accessed Web content to reduce the Internet bandwidth usage and speeding up the client’s download time.
Network Address Translation (NAT) service was configured to share one IP address among several different systems.
In order to accomplish a secure channel to exchange data between two network devices, the Secure Shell (SSH) protocol was added.
The first test shows that the data transfer rate at different time intervals of the day found to be an average of 10.95 Kbps for uploading and 13.7 Kbps for downloading and the second test shows that the network performance improved when squid proxy cache was used.
The data rate found to be 143.3 Kbps average for uploading rate and 376.6 Kbps average for downloading rate.
