As the Internet becomes the critical information infrastructure for both personal and business applications, fast and reliable routing protocols need to be designed to maintain the performance of those applications in the presence of failures. Today's interdomain routing protocol, BGP, is known to be slow in reacting and recovering from network failures. Increasing path diversity by advertising multiple...
With the success of wireless technologies in consumer electronics, standard wireless technologies are envisioned to be deployed in industrial environments as well. Many industrial applications have stringent requirements on reliability and timing. In wired environments, reliability is well catered by field-bus systems. When wireless links are adopted, reliability requirement is significantly more...
To indicate exactly the reliability of large-scale high-speed broadband communication network with domain partition and interconnection, a novel reliability index weighed by normalized capacity is defined, which organically combines connection performance with capacity. The correctness and rationality of the index are demonstrated on the aspects of objective factor of network and subjective factor...
Body sensor networks are an interesting emerging application of wireless sensor networks to improve healthcare and the quality of life. Current research has mainly focused on single-hop networks, although some works clearly show advantages of multi-hop architectures. In this paper, we model probabilistic connectivity in such multi-hop body sensor networks. Instead of using a circular coverage area,...
An embedded gateway serving for the communication between Ethernet and the heterogeneous multilayer interfaces is put forward in this paper. Based on the analysis of the common application requirements in multi-industry, the functions of this system are planned. Collaborative design is adopted in the routing gateway. The models of hardware and software are presented in detail. In the scheme of hardware,...
This paper presents a reliable routing protocol for wireless ad hoc and sensor networks which is based on the DSR routing protocol. The protocol achieves increased reliability through the maintenance of a reliability factor by the nodes in the network. During the route discovery process, the request messages are only propagated to nodes with a reliability factor that is above a threshold value specified...
