Joint Call Admission Control Based on Immune Computing in Heterogeneous Wireless Network

本文研究了单运营商异构网络环境下的联合会话接纳控制问题,给出了一个基于免疫计算的会话接纳控制方案.设计了联合会话接纳控制问题的数学模型,给出了基于免疫多目标优化算法的控制方案框架,并通过仿真实验验证了本文方案.实验结果表明,与文献方案相比,本文设计的接入控制方案在阻塞率和频谱效用之间获得了更好的性能折中,同时更好地兼顾了同一运营商内各个接入网络之间的公平,具有较好应用价值.

To solve the joint call admission control problem in heterogeneous network environment of single operator, a novel admission control algorithm based on immune computing was proposed. The mathematical model of joint call admission control problem was expounded, the framework of admission control solution based on immune multi-objective optimization algorithm was given, and simulation experiments were done to validate proposed solution. Experimental result shows that the proposed solution, compared with other solutions, obtains better performance tradeoffs between recent utility and frequency spectrum, balances prefer- ably each radio access network of the same operator, and has the advantage of good appfication value.
