Enhancing QoS in 5G networks using Self Optimization of Radio Resource Management Parameters The demand for high data rate mobile traffic is increasing tremendously as the world transcends into High Definition (HD) quality applications, video calling, streaming traffic, social media etc. To match these sky-rocketing user demands, increasing traffic and volatile radio environment, mobile networks are continually evolving and becoming more and more sophisticated. While, the trend of mobile networks has been towards an all IP flat network, the network Quality of Service (QoS) metric has shifted from simple voice services to providing high volume data services. The increased network complexity puts a high burden on operation and maintenance costs making the traditional methods obsolete. In this backdrop, the concept of Self Organizing Networks (SONs) was introduced in the 4G mobile network standard by the 3rd Generation Partnership Project (3GPP) to enhance network performance and reduce operational costs. SON is also a significant component in the upcoming 5G mobile standard and thus has received much interest by the research community. SONs behave like an intelligent living organism and adapt to changing environment, resources and traffic loads. Two areas that have a notable impact on network performance are, interference mitigation and coverage adaptation for load balancing and these are the main focus of this PhD research work. We have worked on finding and comparing different self-optimisation techniques based on network Key Performance Indicators (KPIs), to reduce network interference and balance traffic load in the context of SON. In particular, we have applied simple machine learning techniques of Stochastic Cellular Learning Automata (SCLA), simple Q-Learning and Artificial Neural Networks (ANN) QLearning in a fully distributed SON 5G environment with a unique information sharing model among cells, its neighbours and the network. This model is unique in the sense that it depends on a simple distance separation criteria instead of Radio Frequency (RF) environment to identify and define neighbours for information sharing. Interference reduction was done for femtocells, and coverage adaptation for load balancing was done using active antenna tilt model. Test results from network-based simulators based on 3GPP guidelines show that simple SON technique like SCLA adapt quickly, as compared to advance techniques like Q-Learning but are limited in capturing complex network scenarios. The reason being, simple Q-Learning techniques fail to swiftly adjust to changing environment conditions as the number of state variables grow. This is due to increased training time required to build a meaningful Q matrix. ANN showed promising results concerning agility and adaptability to complex changing environments. ANN has the inherent capacity to accept a large number of inputs, reduce the input dimension and adapt to changes as time grows. It is thus concluded, that simple machine learning techniques like SCLA are best suited for enhancing QoS in 5G networks where optimisation input variables are unavailable or unknown like in standalone Femtocell case. However, in scenarios where the numbers of input variable are known and readily available from the network, i.e. cooperative distributed environment, ANN gives better results.
آہ! ڈاکٹر وحید مرزا گزشتہ ماہ ریڈیو سے خبر ملی کہ اس برصغیر کے ایک بہت ہی لائق اور ممتاز اہل علم ڈاکٹر وحید مرزا کی وفات لاہور میں ہوگئی، اس خبر سے بڑا دکھ ہوا، ان سے میری ملاقات زیادہ نہیں رہی، اب سے ۳۵ سال پہلے ۱۹۴۱ء میں دہرہ دون میں تو ان سے برابر ملنے کا موقع ملا، اس کے بعد پھر کہیں ان سے نہیں ملا، مگر وہ اس وقت سے برابر دل و دماغ پر چھائے رہے ہیں ۱۹۴۱ء میں ایک طویل علالت کے بعد دہرہ دون جاکر تقریباً تین مہینے رہا، سرسید احمد خان ہم عصر اور دوست منشی ذکا اﷲ مرحوم کے نامور فرزند جناب عنایت اﷲ صاحب نے اپنی کوٹھی کے دو کمرے میرے قیام کے لئے دے دیئے تھے، اسی زمانہ میں لکھنؤ سے ڈاکٹر وحید مرزا دہرہ دون آکر اپنے خسر جناب رضاء اﷲ کے یہاں مقیم تھے، جو جناب عنایت اﷲ صاحب کے چھوٹے بھائی تھے، انجینئر کے عہدہ سے ریٹائر ہوکر دہرہ دون میں ایک بنگلہ بنایا تھا، دونوں بزرگوں کا وطن دہلی تھا، مگر عنایت اﷲ صاحب نے دہرہ دون ہی میں ڈالن والاکے سیمی روڈ پر منتقل سکونت اختیار کرلی تھی، ان ہی کے بنگلہ کی پشت پر رضا اﷲ صاحب کا بنگلہ تھا، ڈاکٹر وحید مرزا ان دنوں لکھنؤ یونیورسٹی میں استاذ تھے، وہ دہرہ دون آئے تو عنایت اﷲ صاحب کو سلام کرنے آئے، وہیں ان سے میرا تعارف ہوا، قد لمبا اور جسم دبلا پتلا تھا، دونوں گال پچکے ہوئے تھے، کیونکہ منہ کے تمام دانت نکلوا دیئے تھے، پتلون اور قمیض پہنے ہوئے تھے، بڑے متین اور سنجیدہ نظر آئے، خاموش بیٹھے رہے، عنایت اﷲ صاحب کی باتوں کا جواب بہت ہی مختصر طریقے پر دے کر خاموش ہوجاتے، جب وہ اٹھ کر چلے گئے تو عنایت اﷲ صاحب...
When we analyse the preaching of religion by the Holy Prophets (peace an blessing of Allah be upon them) in the background of history of mankind, we come to know that Allah Almighty offered at least a Shari'ah (a code of social, moral and religious conduct) to every Prophet or bound them to a Shari'ah previousl preached by another Prophet before them. Shari'ah is, in fact, based upon the principles and practices to lead life. There had been at least some differences in the Shari'ah different Prophets with regard to the difference of their time and place. It is a proven fact that the followers of a Prophet had always been bound to follow the Shari'ah of their own Prophets. The Shareeya of the Prophet of Islam (peace and blessing of Allah be upon him) is absolutely consummate in every respect and it also fulfills the needs of all times to come. It is because of the fact that Mujtahidin who kept on resorting to Ijtehad. The topic under consideration is an intellectual research analysis of the efforts of Shaykh Ahmad Sirhindi in the field of Ijtehad in the history of Islam.
My Ph.D dissertation is a "Comparative Analysis of Sheikh Ahmed Sarhandi and Shah Waliullah as revivalists". Though much has been written on this topic yet the comparative analysis of both these personalities has never been done before inclusive way with special order. The objective of writing this thesis was to expose the services of the families of Sheikh Ahmed Sarhandi and Shah Waliullah for the
cause of Islam.
I have categorized my thesis into six chapters. The first chapter includes revivalism and its history. The
second chapter is entitled as The Torch-Bearers of the movement of the revival of the Region. This chapter
covers the life span of Sheik Ahmed Sarhandi and biography of Shah Waliullah.
The third chapter presents the back-ground of the reformative achievements. The forth chapter covers
the reformative and the revivalistic achievements. This chapter has further been distributed in three
sections. This chapter vividly describes those revivalistic endeavors which made them Revivalists.
The fifth chapter is about the spread and perfection of the revivalistic task. The first section comprises
the revivalistic endeavors of the successors of Sheikh Ahmed Sarhandi whereas, the achievements of the
successors of Shah Waliullah have been discussed in the second section.
The sixth chapter presents in the comparative analysis of Sheikh Ahmed Sarhandi and Shah Waliullah as
revivalists. In the beginning of the chapter, the meaning of comparative analysis, its beginning,
significance and the rules and the regulations have been discussed. After that, the comparative analysis
has been presented under different headings. In the last portion of the chapter, the allegations put against
these personalities and their impacts have been described and it has been demonstrated who actually
are revivalists and how their thought - provoking teachings can be helpful in today's age of turmoil.
At the end of thesis, the out come of the research, suggestions, punctuation and references have been
mentioned.
