Secure Position-Based Selecting Scheme for WSN Communication

Wireless Sensor Networks (WSNs) found applications in different hostile environments. Addressing messages to a given node or a group of nodes in these situations is a very important and difficult task. Often one should address all nodes from a given area. In this paper we propose a new approach to the addressing problem. Our proposal is primarily destined for broadcast networks but it can be also used in other networks with specific routing protocols. The scheme is based on identification of the spatial position of a node and it is realized by fast cryptographic hash functions. Such a solution makes it possible to address all sensors from a given connected area in an easy, fast and secure way.
