Today, wireless sensor networks are being used more and more, for applications ranging from environment to military use. Wireless Sensor Networks are made up of many small nodes. These nodes are able to sense data such as temperature, light, and humidity. These nodes usually have limited power and transmission range, which in turn limits the lifetime of the network. The data that is collected by these nodes is then sent to a base station. The price of sending the data to the base station is very costly, in terms of energy. In order to reduce the energy used during the transmission of data, we plan to create a method of grouping the nodes in such a manner that each node can communicate with a clusterhead (group leader) then have only the clusterhead communicate with the base station. This will increase the life span of the network by not forcing each node to communicate with the base station directly.
