Optimal Power Consumption in Cooperative WSNs for a Random Distance using 2-D Topology

Authors: Shorouq AL-Eidi and Jamil Ahmad AL-Sawwa

Wireless sensor networks a combination of advance made in the field of analog and digital circuits. A wireless sensor network usually consists of self-organized and installed devices called sensor. These sensors are used to sense, collect and send information in remotely areas, the sensors are deployed and they are able to be installed, organized, and cooperate with each other. However, the sensors are supplied by small batteries, which is difficult to be recharged and replaced in difficult environments, such as natural habitats. Therefore, power consumption is one of the main issues considered in this field. Studies discussed the optimal power consumption in fixed distance, while the random distribution is not considered. This study discusses the optimal power consumption in such grids topology with random distance and variance number of nodes in this topology. The study assumes that the grid consists of 2*2, up to 6*6 nodes. The results show that the diagonal path between the sender and receiver is the optimal path for power consumption, although they were fixed.
