Consider a wireless network made up of units that perform both measurements and communications. These units are totally independent and are capable of recording data from sensors. Ad hoc sensor networks are ad hoc networks that are characterized by decentralized structure and ad hoc deployment. Sensor networks have all the basic features of ad hoc networks but to different degrees for example, much lower mobility and much more stringent energy requirements. The authors analyze the current state of research and evaluate open issues in development of routing techniques in wireless sensor networks.
