Wireless Sensor Network (WSN) depends on the dense deployment of sensor nodes over a wide area. In WSN, battery is the most important resource in sensor nodes. The main objective of sensor nodes is comprised of sensing, processing and for communication. It consumes more energy mainly during transmission of data. In previous papers, virtual backbone scheduling for maximizing network lifetime has been...
To overcome resource conflict occurred in data broadcasting among nodes which are shared and interferential each other on radio channels in sensor network, in the article we propose fuzzy Hopfield neural network(FHNN) in order to solve TDMA broadcast scheduling problem of wireless sensor network. We considered it as discrete energy minimization problem and mapped it into Hopfield neural network with...
In order to take advantage of spatial reuse, graph coloring algorithms are adopted to schedule the links of wireless sensor network that uses TIVIDA mechanism These algorithms color the links with different colors and use the number of colors to determine the length of superframe, then assign the colors to corresponding time slots of superframe. In this paper, the impacts of the assignment on network...
