In wireless networks environment, nodes are powered by exhaustible energy provided by batteries with limited duration. When the energy budget of a node comes to exhaustion, many undesirable situations may occur, ranking from minor alternative route discovery to unbearable network partition. Another situation which has not yet paid attention is one reached when a distributed application requires more...
Wireless sensor networks suffer greatly from their limited battery power whose utilization is increased manifolds as a node has to transmit or receive fairly large amount of data. Several algorithms, some for scheduling battery power e.g. dynamic voltage scheduling, static voltage scheduling, dynamic power management etc and other with emphasis on designing efficient routing protocols have been designed...
In this paper.a wireless sensor network node hardware and software implementation is introduced based on the top grade 8-bit AVR micro-processor ATmegal28L and 2.4 GHz wireless communication chip CC2431. To avoid the shortage of TinyOS, an improved task schedule flow is introduced. Some sensors are used to provide necessary sensing ability. Proper protocols are adopted in MAC and network layers to...
