Low power rendezvous in embedded wireless networks

ln the future, wireless networking will be embedded into a wide variety of common, everyday objects [1]. In many embedded networking situations, the communicating nodes will be very small and battery powered. For this reason, it is crucial that power consumption is as low as possible. A technique for reducing power consumption is to place nodes into a sleep mode whenever possible, and have them occasionally awaken to interact with other nodes. This type of action is referred to as a node rendezvous, and can be used in a variety of different ways. In this paper we consider power-efficient service rendezvous in embedded wireless networks with external triggering. We first define two basic rendezvous mechanisms, namely, server beaconing and client beaconing. We show that server beaconing is preferred when the client arrival rate is below a parameter dependent threshold. Above this level, the use of client beaconing results in lower power consumption. We also consider a hybrid technique wh...
