Low-power design is one of the most important issues in Wireless Sensor Networks (WSNs), where nodes are likely to be largely scattered with constrained battery energy .Transmitting power control is a simple method to make the power consumption down, while network connectivity and excessive interferences should be considered . In this paper ,an optimal Transmitting power is derived by considering average interferences and network connectivity. To make the network energy efficient, we present a novel protocol via Adaptive Rate Control with Optimal Power (ARCOP). Compared with MCP(Maximum Common Power ,e.g. 802.11DCF with fixed maximum power) and Basic protocol, Simulation results show that the new protocol can achieve high average throughput while minimizing Energy Consumption Per Useful Bit (ECPUB).
