The next generation of mobile wireless systems targets to obtain ubiquitous connectivity services for mobile users through heterogeneous wireless networks (HWNs), which integrate cellular network, WLAN, WiMAX, and MANET. It is essential to consider the security issue as one of the main objectives in developing HWNs. In this article, we discuss the security characteristics unique to HWNs and show how attacks against single or multi-hop wireless networks can be translated into powerful attacks against HWNs. We investigate various types of attacks against HWNs and provide an overview of existing solutions for security protection. We also identify underlying challenges in securing HWNs infrastructure and protecting the transmitted information.
