Power-Effective in the Cell Sectorization Using Wide-Beam and Narrow-Beam for Multi-hop Relay Network

Multi-hop relay is a significant topic in the wireless communication and it is provisioned in the 802.16j standards.At present,the major research on multi-hop relay is focused on the capacity,coverage,coordination,throughput,etc.But in this paper,a new concept about power-effective was discussed.Then,two power-effective coverage extension methods using two sectorized cellular approaches were introduced,i.e.,the widebeam three sector cell(WBTC) and the narrow-beam three sector cell(NBTC).Under such topologies,the consumption of power and optimal numbers of base stations(BSs) and relay stations(RSs) with respect to various user traffic densities were investigated.Finally,it is found that the performance of WBTC is better than NBTC.

猫捉老鼠,司空见惯;狗拿耗子,就不免要少见多怪。前些天,电视上就有这样一则趣闻。说一土坑里发现老鼠,有好事者将肥猫放入坑中,谁知肥猫不捉老鼠不说,反倒吓得龟缩一隅任凭老鼠百般蹂躏。围观者惊怪,便又找大狗一只,狗进坑后老鼠还想逞威,可大狗不是吃素的,哪里容得耗子跳梁!于是扑将上去一拍一咬,眨眼间老鼠便一命呜呼。
