Resumen
In this paper, popular routing protocols for Wireless Sensor Networks (WSNs) are studied. There are many issues and challenges that effect routing of data. First, high energy is consumed which reduces network lifetime. Second, security of routing path is another issue due to development in the cryptanalysis against nodes. The aim of this paper is to propose an energy aware routing approach that considers energy level for sensors during cluster heads and routing path selections. Performance, network efficiency and maximizing network lifetime are measured by simulation, analysis and comparison with other well-known mechanisms.
