Rangkaian mikroselular akan menjadi calon yang baik untuk rangkaian mudah alih jalur lebar masa hadapan. Ia dijangka menyokong sambungan kadar bit tinggi untuk ramai pengguna mudah alih pantas jika penyerahan diproses cukup pantas untuk mengurangkan kesannya terhadap keperluan QoS. Salah satu teknik yang dipercayai boleh digunakan untuk antara muka wayarles dalam rangkaian mikrosel sebegitu ialah teknik WLAN (LAN Tanpa Wayar) kerana kadar saluran wayarlesnya yang sangat tinggi. Walau bagaimanapun, keupayaan kurang sokongan mobiliti teknik ini mesti dipertingkatkan untuk dapat mengembangkan penggunaannya untuk persekitaran mikrosel. Sebab mobiliti sokongannya yang kurang adalah kelewatan kependaman penyerahan yang besar disebabkan oleh penyerahan berasaskan perbalahan kepada BS baharu (stesen pangkalan) dan kelewatan pemajuan semula data daripada BS lama kepada BS baharu. Kertas kerja ini membentangkan cadangan LMC (Sel Makro Logik) berbilang pengundian dan dinamik untuk mengurangkan kelewatan yang disebutkan di atas. Bingkai undian untuk MT (Terminal Mudah Alih) dihantar daripada setiap BS kepunyaan LMC yang sama -- sel makro tunggal maya yang merupakan kumpulan multicast beberapa sel mikro bersebelahan di mana MT berkomunikasi. Daripada bertanding untuk medium BS baharu semasa penyerahan, MT bertindak balas kepada pengundian yang dihantar daripada BS baharu itu untuk membolehkan peralihan. Oleh kerana hanya satu BS LMC yang menerima ACK pengundian (pengiktirafan) terus daripada MT, bingkai ACK ini perlu disiarkan secara berbilang kepada semua BS LMC yang sama melalui rangkaian daratan untuk meneruskan penghantaran kitaran pengundian seterusnya pada setiap BS. Lebih-lebih lagi, apabila MT menyerahkan kepada sel baharu, LMC semasanya ditukar kepada LMC yang sepadan baharu untuk mengelakkan persaingan masa depan untuk LMC baharu. Dengan cara ini, MT boleh melakukan penyerahan antara sel mikro LMC dengan lancar kerana sumber berlebihan dikhaskan untuknya di sel jiran, tidak perlu bersaing dengan orang lain. Keputusan simulasi kami menggunakan simulator OMNeT++ menggambarkan pencapaian prestasi skim LMC berbilang undian dan dinamik dalam menghapuskan kependaman penyerahan, kehilangan paket dan memastikan daya pemprosesan pengguna mudah alih stabil dalam keadaan beban trafik yang tinggi walaupun ia menyebabkan sedikit overhed pada sel jiran.

Abstract: A microcellular network will be a good candidate for the future broadband mobile network. It is expected to support high-bit-rate connection for many fast mobile users if the handover is processed fast enough to lessen its impact on QoS requirements. One of the promising techniques is believed to use for the wireless interface in such a microcellular network is the WLAN (Wireless LAN) technique due to its very high wireless channel rate. However, the less capability of mobility support of this technique must be improved to be able to expand its utilization for the microcellular environment. The reason of its less support mobility is large handover latency delay caused by contention-based handover to the new BS (base station) and delay of re-forwarding data from the old to new BS. This paper presents a proposal of multi-polling and dynamic LMC (Logical Macro Cell) to reduce mentioned above delays. Polling frame for an MT (Mobile Terminal) is sent from every BS belonging to the same LMC -- a virtual single macro cell that is a multicast group of several adjacent micro-cells in which an MT is communicating. Instead of contending for the medium of a new BS during handover, the MT responds to the polling sent from that new BS to enable the transition. Because only one BS of the LMC receives the polling ACK (acknowledgement) directly from the MT, this ACK frame has to be multicast to all BSs of the same LMC through the terrestrial network to continue sending the next polling cycle at each BS. Moreover, when an MT hands over to a new cell, its current LMC is switched over to a newly corresponding LMC to prevent the future contending for a new LMC. By this way, an MT can do handover between micro-cells of an LMC smoothly because the redundant resource is reserved for it at neighboring cells, no need to contend with others. Our simulation results using the OMNeT++ simulator illustrate the performance achievements of the multi-polling and dynamic LMC scheme in eliminating handover latency, packet loss and keeping mobile users' throughput stable in the high traffic load condition though it causes somewhat overhead on the neighboring cells.
