In Wireless Sensor Network, sensor nodes are low powered and small devices mainly deployed in critical regions. Due to their energy constraint issues, many routing algorithms have been developed for efficient forwarding of data for minimizing energy consumption. Considering the static sink, nodes near the sink will have more load for routing data, therefore sink has been made as mobile. Now the sink...
SpaceWire is a full-duplex, point-to-point, high-speed serial data transfer standard which is intended for use in further on-board spacecraft, space missions and applications. However, space environment is harsh and complex which requires a communication network with high reliability. It is inevitable that SpaceWire network link fault or SpaceWire equipment damage is able to change the SpaceWire network...
We focus on designing efficient flow monitoring algorithms in SDN/OpenFlow by fully exploiting all three polling mechanisms, poll-single, poll-some and poll-all. Notably, the poll-some mechanism has not been adopted by any existing flow monitoring algorithm due to the inflexible match structure standardized in the early version of the OpenFlow specification. To enable the poll-some mechanism, we need...
The technological developments in microelectronics have enabled the integration of capacity for realization of several important tasks for monitoring the environment in very small sensor named components with low cost and low power consumption.
