Sensor networks are wireless networks with peculiar properties that require specific attention to be properly managed if their performance and dependability have to be taken care of. In fact, both the usually hard environmental conditions where sensors are deployed and the scarcity of node resources determine overall critical working conditions that(More)
Providing efficient mechanisms to reduce consuming power and optimize computing resources is one of the most important goals to be pursued when an efficient utilization of sensor networks has to be addressed. To reduce power consumption at the MAC level, sensor networks usually make use of a scheduled contention protocol that adopts listen/sleep cycles.(More)
Wireless sensor networks are a new emerging area where swarm intelligence can be applied with interesting implications. In fact, a strong analogy between unicellular organism colonies and wireless sensor networks can be emphasized: a sensor network can be viewed as a "colony" of simple, scarce resource nodes that, autonomously, are able only to perform(More)
Resource reservation in wired networks is a relatively mature area, with some available solutions already o n the market. Due to the increasingly growing diflusion of mobile terminals and services, the study of the issues concerning the management of mobility in IP-based networks i s also arising increasing interest. The combination of both issues is(More)
Mobile Networks are requested to provide several added value services with different QoS levels. An efficient Call Admission Control (CAC) is one of the strategic components that a network management policy requires, which defines how to allocate network resources to roaming and new users. We assume a hierarchical network architecture constituted of several(More)
The basic concept behind a Wireless Sensor Network is to deploy a large number of sensor nodes able to acquire and process data. Most of WSNs applications require sensor nodes to maintain local clocks both to determine the events order and to provide temporal information to measured data. Thus, providing a powerful synchronization system is one of the most(More)
