The emerging applications using sensor network technologies constitute a new trend requiring several different devices to work together and partly autonomously. However, the integration and coordination of heterogeneous sensors in these emerging systems is still a challenge, especially when the target application scenario is susceptible to constant changes.(More)
This paper proposes an efficient heuristic for solving the minimum-intracommunication clustering problem in energy-and resource-constrained ad hoc networks. The heuristic organizes the network in clusters aiming to minimize a given cost function. The function used measures the total communication cost between all nodes within the cluster, keeping a minimum(More)
This paper presents a basic and an extended heuristic to distribute operating system (OS) services over mobile ad hoc networks. The heuristics are inspired by the foraging behavior of ants and are used within our NanoOS, an OS for distributed applications. The NanoOS offers an uniform environment of execution and the code of the OS is distributed among(More)
—Sensor networks are being used in several emerging applications not even imagined some years ago due to advances in sensing, computing, and communication techniques. However, these advances also pose various challenges that must be faced. One important challenge is related to the autonomous capability needed to setup and adapt the networks, which(More)
