分析OPNET仿真環境中現有的無線信道建模方案,針對其在多信道仿真中的問題,提出一種新的無線信道建模方案,以彌補原有方案在節點進行信道切換時無法實時偵聽信道狀態的缺陷,保證動態多信道環境中物理載波偵聽的實時性.通過對無線自組織網絡多信道MAC層協議的仿真及仿真數據的分析,驗證了新方案適用于多信道網絡的場景仿真.-Analysis of the existing simulation environment OPNET wireless channel modeling programs, for

In today’s most of the Adhoc networks needs the reliable connection to transfer the data. Most number of data packets loss is experienced in the Adhoc networks due to Transfer control protocol(TCP)’s high channel error rate and link failur

Abstract—In this paper we propose the channel assignment scheme for multi-channel wireless mesh network (WMN), where each mesh router is equipped with multiple radio interfaces. In real WMN the number of radio interfaces is much higher than t

Spectrum Aware and Energy Efficient MACProtocol for Cognitive Radio Sensor Network Designed a spectrum aware multichannel asynchronous duty cycle approach which caters to the requirements of both the domains. The simulation results are also compar
