Ensuring transportation network security is one of the most daunting challenges confronting homeland security agencies today. Significant research has been dedicated to model and analyze the vulnerability of transportation systems, yet notably fewer studies propose specific strategies for deploying defensive technologies to safeguard these systems. The ultimate goal of situational awareness for prevention...
DTN (Delay Tolerant Network) is a new type of mobile Ad Hoc network. Due to its characteristics such as long communication delay, high dynamic topology, it is difficult to maintain the stability of end to end paths. Therefore, design of effective and reliable routing algorithms has become the key issue in DTN. To avoid random and blindfold forwarding in Spray and Wait routing, a DTN routing algorithm...
The study of the multicast routing protocol of multi-constrained is important for the development of the high performance network. The aims are the multi-constrained network model and the definition of the formula of every constrained characteristic measurement. However, it is a NP-complete problem. In order to gain the approximative solution, many heuristic algorithms have been designed by filling...
