Sensor system comprising of hubs with restricted battery power and wireless communications are deployed to collect useful information from the environments in an independent way, and in this manner can uphold bottomless requisitions such as habitat monitoring, moving target tracking, and fire detection. Different sensor nodes for different application can be embedded in the same network. Data sampled by different sensor nodes have much redundancy. Data aggregation has been widely recognized as an efficient method to reduce energy consumption in wireless sensor networks.
