Secure many to many routing for wireless sensor and actuator networks

Abstract

A new secure power aware many-to-many routing protocol for wireless sensor and actuator networks is introduced. The protocol has two versions. The first version is designed for networks where every node transmits at the same power level. The second version is for the case where nodes can individually adjust the transmission power according to the channel conditions and communications distance. In both versions, actuators are registered for sensed data, and every intermediate node that relays registration messages authenticates them through an efficient and secure protocol. When sensor nodes have data, they are sent directly to the actuators registered for that type of data by using a secure many to many routing protocol.
