Optimized Power Schemes for Wireless Sensor Network by using Threshold Techniques

One of the main design issues for a sensor network is conservation of the energy available at each sensor node. Optimal routing tries to maximize the duration over which the sensing task can be performed, but requires historical knowledge. This paper proposes packet profile based (PPB) scheme with certain threshold value 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. Reliability of this scheme is rely on life time of most probabilistic node .This study also compares the result with flooding scheme and PPB without threshold value. Simulation results show that the better energy consumption is achieved by the proposed scheme when compared to the conventional techniques.
