  • For some years, commentators have been predicting the 'convergence' of the Internet and mobile industries. But what does convergence mean? Is it just about mobile phones providing Internet access? Will the coming together of two huge industries actually be much more about collision than convergence? In truth, there are lots of possibilities about what convergence might mean, such as: • Internet providers also supply mobile phones - or vice versa, of course. • The user's mobile phone is replaced with a palmtop computer. • The mobile Internet leads to a whole range of new applications.

  • In a prior edition of this book the preface commenced with the paraphrase of an old adage in an era of evolving local area networking technology: Ethernet is dead—long live Ethernet! Although advances in communications technology continue to occur at a rapid pace, that paraphrase continues to be valid. Within the past decade, the bandwidth of 10 Mbps Ethernet was advanced by a factor of one thousandwith the introduction of a series of enhancements to the original Ethernet specification. First, Fast Ethernet resulted in the bandwidth of Ethernet increasing by a factor of 10 to 100 Mbps.

  • Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed over a wide geographical area, indoor or outdoor

  • Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where the data can be observed and analysed. A sink or base station acts likean interface between users and the network. One can retrieve required information from the network by injecting queries and gathering results from the sink.

  • This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.
