Self-organized Cluster Based Multi-hop Routing for Wireless Sensor Networks

摘要

It is difficult to apply other criteria techniques into wireless sensor networks. Since, sensor nodes are generally very small and have scarce resources. The energy efficient routing to prolong the life time is the major research issue in wireless sensor networks. Many researches proposed cluster-based schemes to reduce energy dissipation. These schemes have to maintain the information of overall nodes or create an imbalanced cluster formation. To solve these problems, we propose a self-organized clustering based on the multi-hop routing. In our proposed scheme, clusters are organized efficiently through the extension of clusters in distributed way without any location data. According to performance evaluation using NS-2, the proposed scheme increase the network lifetime longer than the previous schemes.
