Shivani Thakur, Abhay Bindal . Review on a Node Scheduling based on Partition for WSN. International Journal of Computer Applications. 72, 3 ( June 2013), 8-11. DOI=10.5120/12472-8865
WSN can have a node scheduling based on partition. Employment of such technique can reduce energy consumption of wireless sensor nodes and prolong the network lifetime. Firstly the monitoring area was partitioned into equal virtual grid, according to which the algorithm has two working mode one is monitoring mode and other one is tracking mode. In case of former only one node worked in each grid according to scheduling cycle for the reduction of energy consumption, which balances the work among the nodes and also enhances the lifetime of WSN. In case of latter more nodes were woken up to get the précised minutest details without losing the target. This is the effective lifetime that could be stressed or changed accordingly. The schedulable node set was being made in which nodes can work in their turns and the coverage and connectivity is being discussed. In order to control energy consumption as little as possible a threshold was kept for the waking up and sleeping of sensors. The simulation results show that the node scheduling brings results both in network effective lifetime and in energy consumption and this algorithm prolongs the lifetime of the network twice than PEAS.
