ABSTRACT:

wireless sensor network (WSNs) are composed of numerous sensor nodes WSNs are composed of numerous sensor nodes wsns sensor node detects the corresponding event and sends it is the sink via intermediaries.each node in WSNs are driven by limited power supply.hence power possess by each node in MSNs would be optimized. in this paper we propose dynamic routing based power optimization method (DRBRO) which route the packet based on energy posses by cash node and reduce traffic posses by each node.in case of ideal state nodes are driven by limited power.hence all the nodes in WSNs can be efficiently utilized efficiently which extends the life of each node in WSN to its maximum in addition we propose the relationship between routing traffic and power optinization.
