The electronic parking meter includes a microcontroller, an input interface, an output interface, communications devices and a power supply. The microcontroller receives instructions through the input interface from a user wishing to purchase parking time, controls the output interface to provide parking related messages or indications, and controls the electronic parking meter's communications with other devices through the communications devices for transmitting and receiving information and data. The power supply, which converts a battery pack voltage up to the operating voltage, may include an isolation transformer and a flyback switcher. The parking meter is maintained in a sleep mode as a default state, is placed in a schedule wake-up mode at a predetermined frequency for a predetermined short period of time to carry-out maintenance functions, and is only placed in an event wake-up mode for the time required to process major events, such as coin chute, card reader or communications port interrupts. The maintenance-free life of the parking meter is extended by using more of the energy that is available in standard battery packs and by decreasing energy consumed in the parking meter to carry out its functions through the three operating modes including the periodic schedule wake-up mode.

Method for designing multi-channel opportunistic routing protocol (MCORP) in cognitive radio sensing network (CRSN)
InactiveCN103781145AOvercoming the Unstable FeaturesHigh reliability of data transmissionNetwork topologiesHigh level techniquesNODALJoule
The invention provides a method for designing a multi-channel opportunistic routing protocol (MCORP) in a cognitive radio sensing network (CRSN). In the method, the priority orders of competitive nodes of each node are determined by weighing the residual electricity amount of the competitive nodes, and delivery ratio and ETX between the node and the competitive nodes thereof. The delivery ratio and the ETX of each link are obtained by calculating the average value of all channels in the network. Energy consumption is increased while a competitive node set is enlarged. In view of the finiteness of the energy of nodes, weighing is required to be considered between the delivery ratio and the energy when the value of the competitive node set is selected in order to decrease energy expenditure. For this purpose, the invention provides an evaluation index EDP (expected energy delivery ratio per joule) in order to weigh the relation of the delivery ratio and the energy. A simulation result further proves that the routing protocol provided in the invention has better performance than a multi-channel routing protocol (MCR) in aspects of throughput and data packet loss rate.
