A Network of complex sensor nodes equipped with limited sensing, computing, and radio communication capabilities is called a Wireless Sensor Network (WSN). The sensed data must be gathered and transmitted to a base station where it is further processed for end-user queries. Since the network consists of low-cost nodes with limited battery power, power efficient methods must be employed for data gathering and aggregation in order to achieve long network lifetimes. This paper proposes Packet Profile Based (PPB) scheme to increase the battery power of sensor node. Profile based scheme is based on probability of past information of packet transfer, and save this information as a small data base of each node. This paper also compares the result with flooding scheme.
