Abstract

Wireless Sensor Networks (WSNs) comprised of small nodes embedded with sensing, computation and wireless communications capabilities. Power management, routing and data aggregation techniques have been specifically designed for WSNs where energy consumption is a critical design issue. The emphasis, however, has been laid on the routing protocols which can be different from each other depending on the application, operation and network architecture. In this paper first the design issues for routing protocols in WSNs are discussed after that a comprehensive survey of different routing techniques are given.
