Abstract

The energy consumed by topology maintenance could be higher than that in the initialization stage and the cost will increase steadily with the turns of maintenance process. Therefore, when design a self-organization protocol for WSN, not only initialization cost should be considered but also the maintenance cost in the whole lifetime. Moreover, to reduce the footprint on system resource, the maintenance process should be integrated with the initialization process but not separated. We propose a localized and integrated topology maintenance algorithm in this paper. This algorithm could maintain the topology in a localized manner and the maintenance process is integrated with the initialization process by nature. Simulation results show it has less energy cost in the network lifetime than two other typical protocols.
