Energy conservative data transmission using Z-Mac technique in wireless sensor network for environmental monitoring

Wireless sensor networks (WSN) needs a communication protocol that is very efficient in Energy to reduce the consumption of energy to the maximum. The energy, memory, processor, low range bandwidth and communication of the sensor nodes are taken as resource constrained. The fading and irregularity of radio in multi-hop cause are the unfavorable collision caused by WSN that reduces the sensor networks lifetime. Wireless sensor network in agriculture such as monitoring of environmental conditions like weather, soil temperature, soil fertility, weed-disease detection, precision agriculture, automated irrigation facility, storage of agricultural products. Limited battery usage is enough to make the sensor nodes operate. But the battery power is much difficult to be replaced or recharged, when the entire sensor nodes die which in turn affects the overall performance of the network. By assimilating interactive sending and receiving nodes selection the scheme proposed extends the clustering algorithm and within clusters it enables multi-hop transmissions. In efficiency of energy terms and solodity the proposed systems performance is evaluated. Results after simulations shows that by assuming tough lifetime of the network scheme saves tremendous energy among the cluster could be attained.
