Average Reviews:
(More customer reviews)The editors have put together an excellent compendium of possible and plausible future directions for the development of personal networks. These refer to various computing devices that have the ability to communicate wirelessly. Where it is expected that the devices are often owned by individuals. Think cellphones, laptops, e-book readers, cameras and the like.
One requirement is that clusters can be formed, where the person's devices cannot directly talk to every other of those devices. This leads into the need for encapsulation and tunnelling in some longer range network [like the Internet]. Possible ways to do this are mooted.
Another requirement is for the user/owner to have to do as little as possible technically. What can be handled algorithmically by a device should be done as such, to reduce cognitive burden on the user.
Existing wireless protocols like Bluetooth, WiMax and 802.11 are also studied in the book; largely from the viewpoint of how these have some limitations. Yet the text takes care to remind us that any future device in a personal network will likely need to be able to use one or more of these protocols, because of their existing widespread deployments.
What is notable is the current lack of much interoperability of devices that can automatically connect to each other using different protocols, and using higher level cognitive contextual information to direct data flow and storage. The book has examples of future user interactions. Where a hypothetical user possesses several devices and moves, with these devices, from home to car to workplace. The gist is that devices should somehow recognise each other as being in her Personal Network, and be able to cooperate in allowing each other preferential access to each device's resources.
