Abstract
This article presents a role dynamic management algorithm for sensor devices. The network scenario considers a wireless sensor network in which each node can assume different roles. Specifically, attention is focused on two different roles: the active and the passive role. When a sensor device assumes an active role it uses a greater amount of energy greater than the passive role. The scope of this work is to introduce a dynamic management strategy to better distribute the energy in the network varying dynamically roles of the nodes under different mobility conditions. This dynamic algorithm is applied to an energy-efficient protocol based on a cross-layered approach (ESR and EMAC) and which ensures a good node lifetime. Two different algorithms have been developed to ensure a dynamic management of the node roles with the ESR and EMAC approach. Both these approaches have been evaluated through a simulation tool OMNeT++ and their performance have been compared with the original ESR and EMAC.
