ALEACH: Advanced LEACH routing protocol for wireless microsensor networks

A wireless network consisting of hundreds or thousands of cheap microsensor nodes allow users accurately monitor the characteristics of the remote environment or detect an event. As the sensor nodes have limited energy resources, so the routing protocol designed for the wireless sensor networks should be energy efficient and provide low latency. For this reason, we propose advanced low-energy adaptive clustering hierarchy (ALEACH), a clustering-based protocol architecture where nodes make autonomous decision without any central intervention. ALEACH proposes a new cluster head selection algorithms that enables selecting best suited node for cluster head, algorithms for adaptive clusters and rotating cluster head positions to evenly distribute the energy load among all the nodes. Simulation results show that ALEACH can improve system life time and energy efficiency in terms of different simulation performance metrics.
