All these existing and upcoming networks, combined

together, are promising a globalscale distributed

infrastructure

for

all-time everywhere communication,

known as

Pervasive Communication,

that seamlessly and ubiquitously aids users in

accomplishing their tasks effortlessly.

Computing will be everywhere: pens, cans,pads, boards, coffee machines, alarmwatches, etc.

Invisible and sublime

Communication will be everywhere: amongall devices

Wired and/or wireless

Single-hop or multi-hop

Some of the devices (like refrigerators,ovens, etc.) already have computersincorporated, but without the capability ofcommunicating among each other

PerCom Architecture PerCom architecture can be framed into three broad

areas:

Per Net networking,

PerWare middleware,

PerApp applications

To implement this architecture, all the three sets oftechnologies must be used judiciously

Smartness involves accurate sensing (input)followed by intelligent control or action

(output) between two worlds namely machine and human E.g., a pervasive computing system that

automatically adjusts heating, cooling, andlighting levels in a room depending on an

occupants electronic profile must have some form ofperception to track the person and

also

some form ofcontrol to adjust the ventilation andlighting systems
