An analytical model for performance evaluation of unslotted spread spectrum ad hoc networks is presented by introducing a queuing system and a Markov chain. The model is used to derive packet success probability and expressions for calculating throughput and delay.

通过引入排队系统和马尔可夫链建模方法，建立非时隙扩频ad hoc网络理论分析模型，导出了数据分组成功传输概率，得到了系统吞吐量和时延性能表达式。

A major challenge of the heterogeneous wireless networks is how to jointly utilize the resources of different radio access technologies in an efficient manner. Because of the different system capacities of BS/AP and ununiformity of traffic distribution in different cells, quantities of new calls may be blocked in the overloaded cell in some hot spots; whereas its neighboring under-loaded BS/AP have superfluous bandwidth. In order to raise resource utilization of heterogeneous networks, several novel load balancing strategies are proposed, which combine the call admission control and multi-hop routing protocol of ad-hoc network.

异构无线网络的主要挑战是如何高效利用各种接入网的无线资源，针对异构无线网络基站或AP的容量差异及业务分布不均，导致通信热点地区的新呼叫因负载过重大量阻塞，而相邻轻负载小区却有容量盈余的现象，本文提出了几种联合呼叫接纳控制及ad hoc网络多跳路由算法的负载均衡策略，以提高整个异构网络的资源利用率。

Wireless Ad Hoc networks are self-organized without any immobile basic communication facilities, whose characteristics are wirelessness, multi-hop and mobility.

无线Ad Hoc网络，在没有固定基础设施的情况下，由具有无线通信功能的节点自组织形成，它的主要特点是无线、多跳和移动。
