This paper investigates a specific NP-hard problem by comparing a depth-first search and a depth-first branch-and-bound algorithm as applied to network topology configuration in wireless ad hoc network planning. The vast amount of possible solutions in medium to large NP-hard problems makes algorithm methodology very important. State space algorithms are used to traverse through the solution space...
In this paper, we carry out a detailed investigation on two Train Inauguration Protocols proposed by WG43 for IEC 61375-2-5: ETB Train Inauguration (ETBTI) and Train Topology Discovery Protocol(T2DP). ETBTI uses Layer 2 LLDP to discovery neighbor peers and uses Layer 3 ETBIP to broadcast the information of single node to all the others. On the other hand, T2DP focuses on Layer 2 and modifies LLDP...
There is a strong trend in the photovoltaic (PV) inverter technology to use transformerless topologies in order to acquire higher efficiencies. This paper presents a single-phase five-level grid connected PV inverter with a novel dual reference modulation technique. Two reference signals identical to each other with an offset equivalent to the amplitude of the rectified inverted sine carrier signal...
The cooperative shared tele-operation technology is used to overcome the impact of satellite-earth communication delay and non-structural space environment. To get the appropriate collaborative shared teleoperation system operation sequence, the formal based operation strategy is proposed. Firstly, the task sequence algorithm is introduced. In the algorithm, GSPN (generalize stochastic Petri net)...
Design of Network on chip architectures for multimedia applications is being widely studied. This involves design decisions at various levels of hierarchy. Topology design is one of the significant factors that affect the net delay and the energy consumption of the system. Most of the applications are characterized by bandwidth requirements and latency constraints. The topology must be built satisfying...
Networks on chip (NoC), a new packet-based design method, with a new dependable no deadlock (DND) back-tracking routing algorithm are proposed to implement artificial neural network (ANN). This system is simulated by NIRGAM NoC simulator to get system performance. Experimental results show that this proposed system has higher connection-per-second (CPS), lower communication load than the exiting other...
Multi-objective evolutionary algorithms (MOEAs) have features that can be exploited to harness the processing power offered by modern multi-core CPUs. Modern programming languages offer the ability to use threads and processes in order to achieve parallelism that is inherent in multi-core CPUs. In this paper we present our parallel implementation of a MOEA algorithm and its application to the de novo...
Precise information of MAC layer topology is important for both network management and network analysis. There are many topology discovery algorithms based on the address forwarding tables but they supposed that the network to discovery hasn't redundant links or these algorithms are not effective to discover redundant links. In this paper, we present algorithms based on address forwarding tables (AFT)...
