A RESOURCEFUL ASSESSMENT OF WIRELESS SENSOR NETWORKS
Yogesh Suresh Gunjal, Pasala Raja, P. Sankara Rao · 2013
A Wireless Sensor Network (WSN) contains hundreds or thousands of sensor nodes. The manufacturing of small and low cost sensors became technically and economically feasible due to recent technological advances. To an external base- station (BS) these sensors have the ability to communicate either among each other or directly. A wireless sensor network (WSN) consists of spatially isolated independent sensors to organize physical or environmental circumstances to thoughtfully pass their data through the network to a main location. Some or more important data's may be dropped if congestion occurs in the Wireless Network. By addressing distinguished delivery requirements we handle the above problem. A class of algorithms is proposed based on the congested areas of a network and data priority to enforce differentiated routing. Using simple forwarding rules a basic protocol, called Congestion-Aware Routing (CAR) discovers the congested zone of the network that exists between high-priority data sources and the data sink and dedicates this part of the network to forwarding mainly high-priority traffic. A Mac-Enhanced Congestion Aware Routing (MCAR) is proposed for forming elevated priority paths on the fly for each explode of data, which includes medium-access control (MAC) -layer enhancements and a protocol.
