Theory And Application Of Energy Balanced WSN Route Protocol

Wireless Sensor Network (WSN) provides versatile computing platforms for the applications such as environmental monitoring and military field surveillance. The WSN deployed in these applications are usually faced with harsh environments which makes it very hard or impossible to rechange their node batteries. So it is necessary to fabricate specific protocol for WSN to enable its nodes efficiently utilize their energy. Motivated by this practical demand, a hierarchical protocol architecture with multiple clustering for WSN is proposed in this paper. The cluster heads do not need to transfer information directly to the base station but to the super node through which the information will be transferred to the base station.First through analyzing the typical clustering route protocol, there exist a same problem which is the node energy consume unbalanced. In this paper an energy-efficient multiple clustering protocol is proposed. In this protocol, every node’s residual energy and the node number which belong to one cluster zone are limited. It can prolong the network time by saving the energy of node. This protocol can be more efficient when the base station far from the ordinary node in the MATLAB analyze. Its performance is better than LEACH and HEED.In this paper the hardware platform based on the chip CC2530 is designed and fulfilled, such as oxygen and carbon dioxide sensors. This platform transmits the information through 2.4GHz RF. Meanwhile the system TinyOS is also introduced. Based on this system the protocol MCEE is fulfilled. Last but not the least, the agreement which used for nodes to base station and base station to upper computer is designed. In this way, the nodes could transmit the information in the same standard. An upper computer software also be designed in this paper which is used for real-time display and users could know the history information of WSN. It also has intimate connection with the data-base.
