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...
Congestion control in Wireless Sensor Networks (WSN) has always been a major challenge as contention for medium and limited storage space in nodes lead to loss of packets through collisions and buffer overflows. The congestion problem is tougher for multi-hop mesh networks, required when the deployment area is large compared to the communication range of individual nodes and the network is Ad-Hoc...
Wireless sensor network is a network of sensing devices or nodes which have a limited power supply and processing capability. It is the sensor nodes which sense the environment and report the information gathered from the monitored region to the “sink” or the base station [1]. However the data transferred in a simple WSN is not on the basis of priority, therefore high priority data which needs immediate...
