Abstract

Energy consumption is one of the critical challenges in designing wireless sensor network (WSN) since it is typically composed of resource-constrained devices. Many studies have been proposed clustering to deal with energy conservation in WSN. Due to its predominance in coordinating the behaviors of many players, game theory has been considered for improving energy efficiency in WSN. In this paper, we evaluate the performance of cooperative game theoretic clustering (CGC) algorithm which employs cooperative game theory in a form of 3-agent cost sharing game for energy-efficient clustering in WSN. Furthermore, we compared its performance to a well-known traditional clustering method, low-energy adaptive clustering hierarchy (LEACH), in terms of network lifetime and stability, and total residual energy. The simulation results show that CGC has better performance compared to LEACH due to the cooperation among cluster heads in coalition. CGC has higher alive nodes with stability improvement of first node dies (FND) by 65%, and the improvement by 52.4% for half node dies (HND). However, with the increasing of the number of nodes, the performance of LEACH is getting better compared to CGC.

Abstract

Orthogonal Frequency Division Multiplexing (OFDM) merupakan teknik modulasi multicarrier yang banyak diadopsi oleh berbagai teknologi komunikasi nirkabel untuk memenuhi kebutuhan akses broadband yang kian meningkat karena menyediakan transmisi dengan data rate tinggi. Selain itu, OFDM juga tahan terhadap efek multipath fading. Salah satu permasalahan utama pada sistem ini adalah tingginya nilai PAPR yang menyebabkan penggunaan power amplifier menjadi tidak efisien. Sebagai solusi permasalahan ini, teknik Selected Mapping (SLM) dan Partial Transmit Sequence (PTS) digunakan untuk mereduksi nilai PAPR. Kedua teknik ini dipilih karena efisien dalam mereduksi nilai PAPR. Dari hasil simulasi yang dilakukan terhadap 1000 simbol OFDM, kedua teknik ini memberikan reduksi PAPR yang semakin besar untuk jumlah subblok yang semakin banyak. Selanjutnya, kinerja kedua teknik ini dibandingkan. Dengan jumlah subblok yang sama, SLM memiliki performansi yang lebih baik dalam mereduksi PAPR dibandingkan dengan PTS.
