Title: Secure Energy-Efficient Cluster-Based Routing In Wireless Sensor Networks
Authors: Crabbe, Regina Naa Dedei
Issue Date: 29-Jun-2012
Abstract: Wireless Sensor Networks are increasingly used for various applications, such as home monitoring, environmental monitoring, health monitoring, heavy industrial monitoring, and military monitoring. Sensors are low cost tiny devices with limited storage, computational capability and power. Since numerous sensors are usually deployed on remote and inaccessible places, the deployment and maintenance should be easy and scalable. This study proposes a Secure Energy-efficient Cluster-based Data Routing Protocol for Wireless Sensor Networks based on Symmetric Key Cryptography. The network is divided into a number of clusters and a selected cluster head set within each cluster. The cluster head-set members are responsible for control and management of the network. On rotation basis, a cluster head-set member receives data from its cluster nodes and transmits the aggregated results to the distant base station. Communication between sensor and the sink takes place in four levels; sensor → cluster head → gateway → sink. Encryption of the sensed data is transmitted to the cluster head, which aggregated the data received from the sensor nodes of its cluster before forwarding to the next cluster head on the path or through its gateway to the sink or base station. Sensors do not participate in the routing scheme; their energy is conserved at each sensor node.
