E-health is one of the domains which will need more and more IoT solutions in the future, as it requires short delays for life-dependency situations and safe local storage spaces for privacy matters. The emergency context demands efficient communication and computing capacities, and the cloud vision as well as traditional TCP/IP way of communication cannot really suit these requirements. New approaches...
In wireless sensor networks, Information-Centric Networks (ICN) are used as the next generation network architecture to perform non-TCP/IP communications. Meanwhile, Disruption/Delay Tolerant Networks (DTN) architecture has solved the problem of unable to communicate caused by frequent interruptions, node mobility or lacking of energy by storing the requested data in nodes' memory. However, the users...
The addressing and routing algorithm on hexagonal networks is still an open problem so far. Although many related works have been done to resolve this problem to some extent, the properties of hexagonal networks are still not explored adequately. In this paper, we first create an oblique coordinate system and redefine the Euclidean space to address the hexagonal nodes. Then an optimal routing algorithm...
Networks-on-Chips (NoCs) provides an efficient architectural paradigm as interconnect for state-of-the-art Chip Multi-processors (CMPs). With the increasing development of novel applications in NoCs, one-to-many (multicast) or one-to-all (broadcast) communications are becoming universal and indispensable. The performance constraint metrics, such as power consumption and network latency, are often...
Security and anonymity are important issues for mobile ad hoc network (MANET) routing protocols especially in hostile environments. The adversary nodes can launch traffic analysis against routing information embedded in routing messages and data packets. In this paper we analyze the limitations of the several existing anonymous routing protocols, then we propose a new efficient anonymous on-demand...
Global routing is a fundamental problem in VLSI physical design in which approximate paths for the interconnect (wires) of a circuit are decided. In this paper, a fast, order-free global routing technique is proposed by formulating the global routing problem as an integer linear programming (ILP) problem. A small set of high quality trees, in terms of congestion and length, for each net in the circuit...
