• Resumen

  • Sensor networks consisting of nodes with limited battery power and wireless communications are deployed to collect useful information from the field. Gathering sensed information in an energy efficient method is critical to enhancing the network efficient lifetime in the chain-based wireless sensor networks. In this research, we present three methods for the chain correction in the PEGASIS protocol. One of the main points of weakness of the PEGASIS protocol is the probability of early death of some nodes in the network, its reason is the existence of the long edges in the chain. The proposed methods in this research prevent the long transmission between sensors by using distributed algorithms and correcting the long edges of the chain. Also, we presented a chain correction method in the networks in which nodes perform their operations without awareness of their own locations or that of other network.
