In this paper a Distributed Power Control with Energy Efficient and Reliable Routing Protocol (DPC-EERRP) is developed in order to prolong the network life time with minimum energy consumption to enable continuous data forwarding without incurring energy waste of unrelated nodes by using E3-MAC Algorithm which enables all nodes on the path to stay active and/or increase their duty cycles and all other nearby nodes to sleep. To establish an effective transmission power control mechanism, the dynamics between LQI and RSSI values are studied. In order to minimize energy consumption Energy Efficient forwarding scheme is used in which the data forwarding probability is adaptively adjusted based on the measured loss conditions at the sink. To show the performance of our algorithm we compare the proposed routing protocol with Adaptive Energy Efficient Forwarding Routing (AEERRP). Simulation result shows the proposed scheme performs better than AEERRP
