Existing Wireless Local Area Networks (WLANs), which are dominated by the IEEE802.11b/a/g/n standards, only provide best effort services. These IEEE802.11 protocols that primarily employ Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) mechanism are unable to pro…

This thesis examines the use of modelling approaches in Wireless Sensor Networks (WSNs) at node and sink to: reduce the amount of data that needs to be transmitted by each node and estimate sensor readings for locations where no data is available. First, to contextualise the con…

A Wireless Sensor Network (WSN) consists of a number of nodes, each typically having a small amount of non-replenishable energy. Some of the nodes have sensors, which may be used to gather environmental data. A common network abstraction used in WSNs is the (source, sink) archit…

The development of handheld mobile terminals (MT) capable of operating over both cellular networks and the Wireless Local Area Network (WLAN) is an important step towards the evolution of next-generation integrated networks. The MT is enabled with the choice of selecting between…
