Abstract—In wireless sensor networks, asynchronous sleepwake scheduling protocols can significantly reduce energy consumption without incurring the communication overhead for cl...
Energy is a central concern in the deployment of wireless sensor networks. In this paper, we investigate the energy cost of cryptographic protocols, both from a communication and ...
This paper proposes a spatio-temporal macroprogramming paradigm for push-pull hybrid wireless sensor networks (WSNs). The proposed paradigm, called SpaceTime Oriented Programming ...
This paper presents a novel method for optimizing sliding window based continuous queries. We deal with two categories of aggregation operations: stepwise aggregation (e.g. COUNT) ...
This paper prescribes an incremental procedure to construct roadmaps of unknown environments. Recall that a roadmap is a geometric structure that a robot uses to plan a path betwe...
