Energy consumption analysis of a sensor node working in wireless sensor network
The primary goal of this research work is to develop a close form energy consumption model of a sensor module working in a wireless sensor network. The energy consumption is an important aspect for a battery driven sensor node using in a wireless sensor network. The distinct feature of the proposed energy consumption model is to calculate the energy consumption for bit by bit data transfer of the sensor module. In existing literature there are many energy consumption models available but most of them have considered only one layer energy consumption. Instead of the existing model we have proposed a cross layer based energy consumption. Where together the physical layer and mac layer energy consumption are measured. The usefulness of our proposed energy consumption model is verified by calculation the node lifetime as well as network lifetime for various load in the network. We have also analysis our model with different multiple accesses techniques such as time-hopping (TH) and direct-sequence (DS) multiple access. For reducing the energy utilization of a sensor module we have introduced the sleeping technique by which the sensor node will remain inactive where there is no data for sending to others.
