In many real life applications of WSN, to monitor a wide inaccessible area, a large number of sensor nodes are deployed randomly over the region. When an event occurs, to identify the affected area immediately, it is necessary that the data and the locations of the affected nodes are reported to the sink node with minimum latency. In this paper, for 2D region, using some light-weight distributed in-node...
Schedule based MAC protocols have been proposed to meet the energy constraint of Wireless Sensor Neworks (WSNs). Although existing schedule based MAC protocols such as LMAC and MC-LMAC are energy efficient, they introduce significant end-to-end delivery latency as well as low network throughput. In this paper, a low latency multichannel LMAC protocol, LL-MCLMAC protocol, is presented for WSNs which...
