SEECH: Secure and Energy Efficient Centralized Routing Protocol for Hierarchical WSN

Free registration required

Executive Summary

Wireless Sensor Networks (WSNs) differs from traditional wireless networks in several ways. One of them is energy constraints. Sensor Nodes (SNs) are battery operated, with limited life and difficult to replace, if deployed in hostile environment. Therefore protocols in WSNs must be designed with minimum energy consumption to prolong the network life. In WSNs protocols are designed to minimize energy consumption and preserve the longevity of the network. In this paper, the authors have designed Secure and Energy Efficient Centralized Routing Protocol (SEECH) for hierarchical WSNs. In SEECH, the Base Station (BS) collects information about the logical structure of the network and residual energy of SN. With this information, BS does efficient clustering. Finally, SEECH is compared with LEACH-C protocol.
