Tujuan dari kajian ini adalah untuk menganalisis strategi kerjasama penjimatan kuasa dalam rangkaian telefon wayarles. Sebuah bateri yang digunakan oleh telefon untuk menyokong mobiliti dan kualiti dan masa hidup bateri menjadi isu utama. Sistem ini dapat menjawab masalah ini dengan menerapkan protokol kerjasama bernama kerjasama kod yang cuba untuk mengurangkan pengambilan kuasa. Sebuah model sistem rangkaian wayarles menggunakan teori permainan kooperatif terdiri sejumlah peranti telefon bekerjasama dengan satu sama lain dan dikumpulkan untuk membentuk sebuah kelompok diperkenalkan. Sebuah permainan terdiri daripada tiga bahagian yang satu set pemain, satu set tindakan dan satu set hasil. Dalam sebuah rangkaian wayarles moden, setiap nod menjalankan protokol yang diedarkan perlu membuat keputusan sendiri. Kerjasama kod adalah protokol pengguna wayarles yang terintegrasi kerjasama isyarat dengan pengekodan saluran. Keputusan boleh dihalang oleh peraturan atau algoritma protokol, akhirnya setiap nod, maka adalah agen autonomi, membuat keputusan mengenai saluran kuasa, membawa kehadapan pakej, masa lalu dan sebagainya. Analisis. Sistem model menggunakan bahasa pengaturcaraan NetLogo untuk membuat model kerjasama penjimatan kuasa dalam rangkaian wayarles. Penyelidikan analisis dikumpul dengan menggunakan bantuan jadual dan grafik. Dua parameter dianalisis seperti jumlah peranti telefon dan strategi untuk mencapai penjimatan tenaga. Strategi Egois dan bijaksana digunakan dalam sistem model dan mempunyai cara tersendiri untuk mengurangkan pengambilan kuasa. Keputusan kajian menunjukkan bahawa tahap daya kerjasama rangkaian wayarles bergantung pada strategi kerjasama. Strategi bijaksana merupakan lebih baik seperti dalam rajah 4.3 di bab 4 kerana menunjukkan bahawa penurunan tahap kuasa sejajar nombor peranti telefon meningkat. _________________________________________________________________________________________ The purpose of this study is to analyze cooperative power saving strategies in a mobile wireless networks. A mobile uses battery to support its mobility and quality and battery life time was the main issue. The system can answer to this issue by implementing cooperating protocols named coded cooperation that attempt to reduce power consumption. A system model of cooperative wireless networks using game theory consisted a number of mobile devices cooperate with each other and clustered up to form a cluster was introduced. A game is made up of three components which were a set of players, a set of actions and a set of payoff. In a modern wireless network, each node running a distributed protocol must make its own decision. The coded cooperation is a wireless user protocol that integrates cooperative signaling with channel coding. The decisions may be constrained by the rules or algorithm of a protocol, ultimately each node, then are autonomous agents, making decisions about transmit power, packet forwarding, back off time and so on. The system model used NetLogo programming language to model the system cooperative power savings in wireless networks. The results of performance were gathered with the aid of tables and graphs. Two parameters were analyzed such as number of mobile devices and strategies to achieve power savings. Selfish and wise strategy was used in the system model and has its own way to reduce the power consumption. The results show that the level power of cooperative wireless networks is different according to the strategy of cooperation. Wise strategy was better strategy as the figure 4.3 in chapter 4 shows that the decreasing of power level as number mobile devices increased.
