Security and resource management in heterogeneous wireless networks

无线网络在过去几年中取得了惊人的增长，并日益成为医疗保健、环境、远程教育、普及计算、企业通信、个人通信和紧急服务等广泛应用领域的目标。未来的移动应用将运行在一个不同的无线网络平台上，该平台将集成不同的接入技术，如WiFi、WiMAX、3G+蜂窝，以及可变拓扑自组网、传感器和网状网。其目标是为无线用户提供安全、无缝的接入和无处不在的ABC(始终最佳连接)覆盖。然而，这种网络的成功在很大程度上取决于安全和资源管理技术的有效统一，这是两个关键的设计问题。挑战源于这样一个事实，即不同的接入网络构成了自己的资源约束，并且具有不同的脆弱性。

Wireless networks have seen phenomenal growth in the last few years and are being increasingly targeted in a wide range of application areas such as health care, the environment, distance education, pervasive computing, enterprise communications, personal communications and emergency services. Future mobile applications will run on a heterogeneous wireless network platform that will integrate different access technologies such as WiFi, WiMAX, 3G+ Cellular, as well as variable topology ad hoc, sensor and mesh networks. The objective is to give wireless users a secure, seamless access and ubiquitous ABC ("Always Best Connected") coverage. However, the success of such a network will largely depend on the effective unification of techniques for security and resource management, which stand out as two critical design issues.The challenge stems from the fact that disparate access networks pose their own resource constraints and have varying vulnerabilities.
