Wireless personal area network and wireless sensor networks are rapidly gaining popularity, and the IEEE802.15 Wireless Personal Area Working Group has defined no less than different standards so as to cater to the requirements of different applications. Wireless sensor network (WSN), is a set of sensor technology, computer technology, Network technology and communication technology in the integration...
Vehicle routing is a critical factor in reducing transportation costs. Finding optimal vehicle routes offers great potential to efficiently manage fleets, reduce costs and improve service quality. An effective scheme to manage fleets and determine vehicle routes for delivering goods is important for carriers to survive. In the existing literature, a variety of vehicle routing problems (VRP) have been...
The electricity of sensor nodes in wireless sensor networks is very limited, so it is an important research topic to deploy the sensor nodes and cooperate with an efficient routing algorithm for extending the network lifetime. In the related research, LEACH routing algorithm randomly selects cluster heads in each round to form a cluster network, which may cause additional power consumption and inability...
Low-density parity-check (LDPC) codes form an important subclass of error correcting coding techniques, and its implementation has been hot spot of domains such as signal process, magnetic recording or next generation communication for years. This paper proposes a configurable FPGA implementation of Partition-and-Shift LDPC decoder based on Min-Sum algorithm. An MPEG algorithm is introduced to reduce...
