“…Fujiwara, Iida and Watanabe [36] provide a unicast routing algorithm that allows mobile hosts to find an alternate path to the base station, when the cellular connection fails. The focus of the work is on reestablishing connectivity to the base station via short paths, in response to emergency situations where direct connections to the base station may become sparse.…”

In this paper we introduce JANUS, a framework for scalable, secure and efficient routing for hybrid cellular and Wi-Fi networks. JANUS uses a scalable routing algorithm with multiple channel access, for improved network throughput. In addition, it provides protection against selfish nodes through a secure crediting protocol and protection against malicious nodes through secure route establishment and data forwarding mechanisms. We evaluate JANUS experimentally and show that its performance is 85% of the optimum algorithm, improving with a factor greater than 50% over previous work. We evaluate the security overhead of JANUS against two type of attacks: less aggressive, but sufficient for some applications, selfish attacks, and purely malicious attacks.

“…In emergency applications, network robustness and reliability is a desired requirement. In [13], a hybrid wireless network architecture and a unicast routing protocol is used for collecting information from radio nodes to a base station is proposed for emergency communication. In this network, when a node loses the direct connection with the base station, it switches from the cellular mode to an ad hoc mode, and reaches the base stations via multi-hop.…”

The Information Society Technologies (IST) EUROPCOM project [1] designs and develops an UltraWideBand (UWB)-based ad hoc network for search and rescue operations in disaster zones, especially indoors. The primary application of the EUROPCOM system is to provide position tracking of rescue personnel within the disaster zone. Currently no such technologies or systems exist, which can provide the envisaged functionality. The paper presents the network architecture that was proposed in the EUROPCOM project. The network architecture defines new physical entities and includes a complete protocol stack -from the physical layer up to the application layer. Each protocol layer was tailor-made to the operational constraints and requirements of the EUROPCOM system. The resulting protocol layers are lightweight, selfadaptive, bandwidth-and energy-efficient.

In this paper we investigate and provide solutions for security threats in the context of hybrid networks consisting of a cellular base station and mobile devices equipped with dual cellular and ad-hoc (802.11b) cards. The cellular connection is used for receiving services (i.e. Internet access) from the base station, while the ad-hoc links are used to improve the quality of the connection. We provide detailed descriptions of several attacks that arbitrarily powerful adversaries, whether outsiders or insiders, can mount against wellbehaved members of the network. We introduce a secure routing protocol called JANUS, that focuses on the establishment of secure routes between the base station and mobile devices, and the secure routing of the data. We show that our protocol is secure against the attacks described and experimentally compare the message overhead introduced by JANUS and UCAN.
