Wireless sensor networks: A survey on the state of the art and the 802.15.4 and ZigBee standards

Current trends in smart homes suggest that several multimedia services will soon converge towards common standards and platforms. However this rapid evolution gives rise to several issues related to the management of a large number of multimedia streams in the home communication infrastructure. An issue of particular relevance is how a context acquisition system can be used to support the management of such a large number of streams with respect to the Quality of Service (QoS), to their adaptation to the available bandwidth or to the capacity of the involved devices, and to their migration and adaptation driven by the users' needs that are implicitly or explicitly notified to the system. Under this scenario this paper describes the experience of the INTERMEDIA project in the exploitation of context information to support QoS, migration, and adaptation of multimedia streams.

“…Sensor networks are systems that collect environmental information from sensors that are attached to objects, provide that information to a user, and react to certain events on demand [1][2][3][4][5]. A sensor network is composed of a large number of tiny sensor nodes that monitor the surrounding environment and one or more sink node(s) that collect information from the sensor nodes.…”

Abstract. WSNs are becoming an important topic in the research arena. Their low cost and the wide range of applications where wireless sensor networks can be applied, make them an important research and commercial field in the short term. Furthermore, the IEEE 802.15.4 standard for physical and MAC layer in addition with the Zigbee specification for the network and application layer, are an enforcement for WSNs. Much research in WSNs related topics such as energy-aware, MAC protocols, routing protocols, security, location, etc is being carried out nowadays. An open issue is the interconnection between wireless sensor networks where different approaches can be adopted: bridging (extension devices) and proxying (mainly middleware entities). This paper is focused in the bridging approach for Zigbee networks. Our objective is to establish a Zigbee Extension Device Network for the case where the different clusters can not be connected to the same Zigbee network by using the multihop routing protocol defined in Zigbee. A Zigbee cluster is a set of Zigbee nodes. This paper introduces three different solutions to join the disconnected clusters of the Zigbee Network: a central approach (based on the use of a central station) and two distributed approaches; one of them proposes that each Zigbee Extension Device stores the information of all the other Extension Devices within the network while the other uses a P2P Zigbee Extension Device Overlay Network to join the disconnected Zigbee Clusters. The paper includes the analysis of each solution and the comparison among them.
