Using Two Widespread Backbones to Increase the Lifetime of Wireless Sensor Networks

Limiting energy resource in the sensor networks increases the importance of energy aware protocols. Nonexistence of fixed or predefined infrastructure in the sensor networks compared to radio and case networks, add the necessity of existence such protocols. In this paper, two energy aware rooted virtual backbone have used for collecting and transferring data toward the sink. Each backbone is built such that covers the large numbers of network nodes, so that any node is not a member of both backbones. Simulation results show that alternative usage of two mentioned backbones, have significant influence on the increasing network lifetime. Also we would show that suggested guideline, against existing methods, has not significant effectiveness of changing the size of controlled packet
