A Publish/subscribe Protocol for Resource-awareness in Wireless Sensor Networks
نویسندگان
چکیده
Research has shown that alternating the routes in wireless sensor networks, can extend the network’s lifetime and increase communication savings. Many proposed data dissemination protocols, however, establish paths that guide data on a hop-level basis from sources to sinks. In this paper, we explain why such a tight-coupling (between the data dissemination and data routing) may be desired, even when a locationbased addressing scheme may be available; and describe a novel locationbased publish/subscribe protocol that offers support for the transparent operation of resource-aware routing protocols. Our protocol offers a trade-off between shared event dissemination paths (that can increase communication efficiency) and support for resource-awareness (that allows freedom of notification routing from the publishers to the subscribers).

An efficient symmetric polynomial-based key establishment protocol for wireless sensor networks
An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...

متن کاملQuality-Aware Resource Management for Wireless Sensor Networks
Due to the distributed and resource constrained nature of wireless sensor networks, their design proves to be difficult. We present a resource management framework, which integrates a data-centric lightweight operating system with a publish/subscribe middleware. In this framework, the main system abstraction is data for both local and networked processing. The resultant system software is exten...
