Abstract

Recently Wireless sensor Networks (WSNs) takes interesting researches due to there important and crucial applications. WSNs have limited energy so all researches focused in designing routing algorithms to save energy and to make each one operating for longer possible time. Based Random Efficient Energy (BREERA) is one of WSNs routing algorithms saved energy of the whole network because its sensor nodes needn’t to know any information about their sensor nodes neighbors. This paper suggests two approaches to modify the performance of the routing algorithm BREERA and make a comparison between the performance of the original BREERA and the performance of the modified BREERA. The first suggested method was called weights method which improved the performance of BREERA with the average received messages, lost messages, PDF, and average total energy. Weights method used two cases of energy weights (w1= 0.1 and w1= 0.8). With the value of the energy weight equal to 0.1 obtained higher received messages average, higher PDF average, less lost messages average and less died nodes average. While with the value of the energy weight equal to 0.8, a higher total energy was obtained. The second suggested approach is to limit the number of members for each cluster head which improves the performance of BREERA in received messages, lost messages, died nodes, PDF and total energy .The simulator Net Logo version 4.1.3 was used to design the simulation program of the routing algorithm BREERA.
