Cluster-Based Energy-Efficient Secure Routing in Wireless Sensor Networks

摘要

To get inexpensive resolution of real-world problems such as weather forecasting, measurement of underground water label, traffic monitoring, activity of enemies, animals counting in forest, and so on, wireless sensor networks (WSNs) are widely used. Energy-efficient routing protocol is needed to provide the longevity of network lifetime by reducing power consumption of sensor nodes as well as whole networks. Besides, authenticity of sensor nodes and privacy of sensed data are needed in routing protocol for WSNs to provide secure communications, i.e., sensor-to-sensor as well as sensors-to-base station. Clustering technique provides an energy-efficient topology control approach. A minimum connected dominating set (MCDS) can be discovered by applying clustering technique which reduces power consumption in inter-cluster network routing. Cluster head and route selection can be used to provide an energy-efficient outer-cluster routing in WSNs. Identity-based scheme can be used to provide a secure secret message passing mechanism in WSNs. This paper has ng in wireless sensor network framework (E2SDRSNF) which consists of three proposed components. The proposed Algorithm 1 creates a MCDS which is used to build virtual backbone for energy-efficient inter-cluster routing. Data flows through the discovered virtual backbone nodes to base station via cluster heads which is discovered by applying proposed Algorithm 2. The proposed signcryption technique is used for secure communication in WSNs. The analysis of the proposed framework shows that it can save 2720 nJ/bit/m~2 energy than LEACH protocol for one communication (transmission/receiving) along with the security.
