Synopsis
移动互联网是当今网络技术领域的研究热点之一，目前尚有诸多挑战性问题，如：在宽带无线网络不完全覆盖区域如何提供基本的网络应用，如何缓解流量爆炸造成的网络拥塞，从而提供重要数据的服务质量保证。 本书拟基于针对多媒体和下载类业务的可替代性和内网效应，提出资源后取策略；进一步对现有的效用函数做出修正和调整，提出移动互联网业务统一效用函数，使所有业务的表达式统一。 构建了基于DTN的M2H2DTN（Mobile Multi-Homing Hierarchical DTN-based Internet Access）,提出cache覆盖层以支持后取和预取策略，无需MIP即可支持移动性,具有较好的抗毁性和健壮性，能较好地适应从网络不完全覆盖到全面覆盖的平滑过渡。 建立了基于统一效用函数的非线性规划模型，针对现实中的概率不确定因素，使用不确定理论进一步发展了资源分配模型，实现了算法的实时性。 建立了基于广义k-选播的双渡轮路由算法；根据接入路由器信息矩阵决定候选路由器集合，以效用最大化模型决定数据k-选播到各路由器的带宽和时间。 提出广义k-选播的地址簿通知（ABI）策略，以实现上下文预先转移，从而在初始化和切换过程中减少延迟可能性，减少切换过程中的资源占用率，通过计算说明ABI信令增加极小。最后建立了Pi演算模型，验证了ABI模型的自洽性、正确性，以及对于移动IPv6的兼容性。
