Abstract |
The issue of energy consumption and the age of the network is one of the essential features in the design of the wireless sensor network (WSN), which has led researchers in the field of networks and communications to work on innovative mechanisms to reduce energy consumption in these networks and prolong the lifetime. Experts have suggested several WSN-based clustering protocols, since most clustering protocols are homogeneous, and LEACH and M-GEAR are among the most common examples of these protocols. In this paper, we propose six models for the division of wireless sensor networks (WSNs), in each of these models we will distribute sensor nodes to four zones randomly in the field of the sensor area. We install the cluster heads (CHs) in the middle of the geometry shapes of each area, where the shape of the circle or square or both, will be used, and the location of the sink will be in the center of the sensor area. The sensor nodes that are located around the sink and within the geometric shape used will directly connect to the sink. The external nodes will contact the nearest CHs, and to determine the nearest CHs we will apply the Dijkstra's algorithm. For the average number of dead nodes, the square circle method achieved the best result (73.42), followed by the circle square method which got a result (79,66). The largest number of dead nodes showed when using one square only where the result was (97.15). We make a comparison between the outcomes and M-GEAR and LEACH protocols, our model (square circle) stabilizes energy use within sensor nodes. However, nodes in M-GEAR and LEACH do not stay alive for a long time, they die when the stability period is over. |
