Baru-baru ini, rangkaian multi-hop tanpa wayar menggunakan teknik penyampaian dua hala MIMO telah menarik perhatian ramai kerana kecekapan rangkaiannya yang tinggi. Adalah diketahui umum bahawa rangkaian multi-hop dua hala (MTMN) MIMO boleh memberikan daya pemprosesan maksimumnya dalam topologi seragam lokasi nod. Walau bagaimanapun, dalam persekitaran realistik dengan topologi tidak seragam, kapasiti rangkaian merosot dengan teruk disebabkan kualiti pautan yang tidak sama rata. Tambahan pula, kapasiti hujung ke hujung juga merosot pada SNR tinggi disebabkan gangguan jauh (overreach) yang wujud dalam senario geganti berbilang hop. Dalam kertas kerja ini, kami memberi tumpuan kepada beberapa skim peruntukan kuasa untuk meningkatkan prestasi kapasiti hujung ke hujung MTMN dengan topologi tidak seragam dan gangguan jauh. Tiga skim peruntukan kuasa konvensional dirumus semula dan digunakan di bawah model sistem MTMN. Dua yang pertama ialah kaedah terpusat, iaitu, Peruntukan Kuasa (EPA) berasaskan Eigenvector yang menggunakan algebra linear dan Peruntukan Kuasa Optimum (OPA) menggunakan pengoptimuman cembung. Yang terakhir ialah Agihan Kuasa Teragih (DPA) menggunakan teori permainan. Daripada analisis berangka didapati bahawa skim peruntukan kuasa adalah berkesan untuk MTMN dari segi peningkatan kapasiti hujung ke hujung, terutamanya dalam susunan nod tidak seragam dan pada SNR tinggi.

Abstract: Recently, wireless multi-hop network using MIMO two-way relaying technique has been attracted much attention owing to its high network efficiency. It is well known that the MIMO two-way multi-hop network (MTMN) can provide its maximum throughput in uniform topology of node location. However, in realistic environments with non-uniform topology, network capacity degrades severely due to unequal link quality. Furthermore, the end-to-end capacity also degrades at high SNR due to far (overreach) interference existing in multi-hop relay scenarios. In this paper, we focus on several power allocation schemes to improve the end-to-end capacity performance of MTMN with non-uniform topology and far interference. Three conventional power allocation schemes are reformulated and applied under the system model of MTMN. The first two are centralized methods, i.e., Eigenvector based Power Allocation (EPA) which employs linear algebra and Optimal Power Allocation (OPA) using convex optimization. The last one is Distributed Power Allocation (DPA) using game theory. It is found from numerical analyses that the power allocation schemes are effective for MTMN in terms of end-to-end capacity improvement, especially in non-uniform node arrangement and at high SNR.
