This paper proposes a dynamic slot scheduling for tasks having different time constraints executed over wireless sensor networks (WSN). These tasks may have different priorities. They are usually repeated periodically. We present an algorithm which is able to provide a dynamic scheduling procedure for all tasks. In the actual version, the scheduling algorithm is executed on the network coordinator...
The design of efficient Wireless Sensor Networks (WSN) is a very hot topic nowadays. The efficiency could be observed at many levels, from the application layer to the physical part. In order to get better performances over WSN, many parameters could be considered: the application type, the routing protocol, the MAC protocol, the physical protocol, the radio range of nodes, the topology of the networks...
TCP is known to exhibit poor performance in Over wireless networks. Various parameters may be considered to configure the network functioning with multi-hop wireless connectivity. Many routing protocols could be used over WSN. In this paper, we show that the choice of the routing protocol (and its parameters) will surely have an impact on the whole network functioning. We focus, in particular, on...
